Not content to over-block or over-filter perfectly innocuous websites, it seems that the UK nanny state's ineffective over-cautiousness is spreading… to TV programmes.

Note the warning in the programme info (shown on my, generally pretty good, Humax Fox T2) for a TV show depicting an elderly couple pottering gently along the canals of Wales:

canalJourneysInfo

Needless to say, the programme contained no "very strong language", nudity, violence or indeed sexual scenes!

Although occasionally they did grumble about the weather, and there was the odd swear word when their boat bumped against a canal wall…

If you visit certain sites using Google's Chrome browser, and give the site permission to use your computer's microphone (to use speech recognition navigation etc), a researcher has discovered that the website could keep your microphone on even when you've left the site and think it's off - with no warning indicator that it's still on.

To secure your computer and stop sites using this vulnerability to eavesdrop on you using your mic, El Reg has suggested that you simply disable websites' access to your mic and camara. Here's how to do that, with pics:

1. In Chrome, go to the Settings menu (top right, click the 3 horizontal lines icon), then choose the Settings item from the drop down.

2. The Settings page comes up. Scroll all the way down to the end, and click "Show advanced settings":

image

3. Now in the "Privacy" section that appears (which in my view is an essential basic requirement and not an "advanced" setting, but another time…), click the "Content settings button:

image

4. Then you have to scroll down again to find the Media section, and make sure you select "Do not allow sites to access my camera and microphone", then click the "Done" button.

image

That's it! Obviously you'll have to change it if you actually want a particular site to access them, but remember to change it back afterwards.

I rarely use Chrome myself (here's reasons why I don't use Chrome), and this sort of security issue isn't exactly going to persuade me to change my mind!

If you'd like to right-click on a Word or Excel document in Windows Explorer to open it as read-only, supposedly you should be able to hold down the Shift key, rightclick on the filename, and there should be an option to "Open as Read-Only".

image

However, choosing this Shift-rightclick option doesn't actually open the document as read-only. This seems to be a known bug in Office 2003 and Office 2007, and also in Office 2010 and Excel 2010.

There's one workaround and one fix.

Open in protected view

The workaround is that, if you Shift-rightclick on a Word or Excel .xls file in Windows Explorer, there's also an option to "Open in Protected View".

Choose that, and it works pretty much as read-only: you can't change anything, you can't save, but you can copy/paste from that document. This works for Excel as well as Word.

Rightclick context menu item

What solves the problem completely in Word, which I used myself, is to edit things to add a new rightclick Open Read-only context menu option that actually works to open Word documents as read-only. I based this solution on a combo of this post (which wasn't actually on opening read only) and this page (about opening read-only, but for XP only, not later versions of Windows).

Here's how to add a right-click context menu item to open Word files as read only, properly - works for me using Windows 7 and Word 2010:

First, download FileTypesMan (free, but donate if you can, the man certainly deserves it!) - you have to scroll quite a way down for the "Download FileTypesMan" link (I used "Download FileTypesMan for x64" as my computer is Windows 7 Pro 64-bit).

Next, unzip/extract the files (rightclick on the zip fiule downloaded and Extract all to create a new unzipped folder) and open the new folder, then run FileTypesMan.exe.

On the left, scroll down till you find and highlight .docx (or use menu Edit > Find and and type docx to find it, make sure you then highlight that line):

image

Now in the menu choose Actions > New Action (or press Ctrl-n).

In the box that pops up, fill it in like this (and see diagram just above the list):

image

  • Action name - I used  "Open read-only" without the quotes, you could just use "Read only" etc as you prefer
  • Menu Caption - I used "Open read-only" again
  • Command-Line - you can click Browse to find your Winword.exe under Program Files or Program Files (x86) (you will have to drill down to find Microsoft Office, Office14 or Office11 etc depending on your version), or Select from Running Programs if Word is already running, which is the easiest. You could alternatively enter the full path to Winword.exe, with quotes around it, as shown below, but it's easiest to Select from Running Programs (you can launch Word just before you click Select and it should work, just scroll down to find it in the "Select Process" list, possibly to the end):image

After you've used Browse or Select, it will fill in the Command-Line box for you with something like this:
"C:\Program Files (x86)\Microsoft Office\Office14\WINWORD.EXE" "%1"

Now, you have to edit what's in the Command-Line box, by inserting after the "%1" the following (which you can copy/paste from the next line) - just after the 1 but before the close double quotes, and make sure there's a space between the 1 and the first /:
/h /n /dde

In my case, the Command-Line box ended up reading like this:
"C:\Program Files (x86)\Microsoft Office\Office14\WINWORD.EXE" "%1 /h /n /dde"

Next, in the DDE section in the Message box, you should enter  the following, which again you can copy/paste:
[AppShow][REM _DDE_ReadWriteOnSave][FileOpen .Name="%1",.Revert=0,.ReadOnly=1]

(In the Application box you can enter Word if you like, but it will still work even if you don't.)

Finally, click OK. This adds a new Action to the bottom half of the FileTypesMan window, which you can doubleclick to edit in future.

Now, when you rightclick (no need to hold down the Shift key) a docx document in Windows Explorer, you will have a working "Open read-only" menu option (or whatever title you gave it in the "Menu caption" box above).

Furthermore, in FileTypesMan you can select (in the lefthand column) the type .doc for old-style Word documents, and rinse and repeat the steps above, if you wish.

Excel protected view - rightclick only

For Excel spreadsheets, unfortunately the above fix doesn't work, so you have to open them in protected view.

But to make life easier for yourself, you can use FileTypesMan to change things so that you don't have to Shift-rightclick to get the "Open in Protected View" menu option. Here's how to get that option to display just on a simple rightclick:

In FileTypesMan, find and highlight.xls on the left (scroll or search, as with docx above).

image

Now in the bottom half of the window, find and doubleclick "ViewProtected" (outlined in red above).

In the box that pops up, UNtick "Extended", and OK:

image

Now a simple rightclick, as opposed to Shift-rightclick, will call up the "Open in Protected View" option.

Which hard drive to buy? A helpful report by cloud backup provider Backblaze, which uses consumer hard drives, summarised its experiences with over 27,000 drives: of the following 3 brands, Hitachi did best in terms of both annual failure rate and cumulative survival rate (see the report for detailed info on specific models etc). The survival rates over 3 years were:

  1. Hitachi 96.9%
  2. Western Digital 94.8%
  3. Seagate 73.5%.

Interestingly, the latter two reflect my own experience.

I use 4 external hard drives as standard. Two are Seagate and two are Western Digital (WD). One is for my documents (I moved 'My Documents' and similar folders from C drive to an external drive, to protect myself against Windows problems or C drive failing - I wish Microsoft would store user data in a different partition from Windows!). The others are for backup.

One WD recently died, but I've had it for years, and the other one (equally old) is still going strong. One 2TB Seagate also died just after that - but it's less than a year old! And to add insult to injury, one of my WD drives was bought to replace a drive that died a few years ago - a Seagate, again. So, to add my own review, the failure rate I've personally experienced is 2 Seagates (including quite a new one) to 1 WD.

That's nowhere near as statistically significant as Backblaze's results, of course. Still, I'll have to buy at least one more hard drive soon given the 2 dead ones - and guess which brand I'm considering now? Hitachi!

I'm thinking of getting this one:

Or this 2TB one (though two of the 1TB seems better value, and one customer says the 1TB is USB 2.0-compatible, which I need as my KVM switch is USB 2.0 and I don't want to buy another one till the price of USB 3.0 KVM switches with DVI comes down a lot more!):

 

Backblaze noted that WD acquired Hitachi's disk drive business a year and a half ago, but given that WD ranked only just behind Hitachi, I'm not too worried about buying those Hitachi drives. Also, entirely subjectively, a relative who's a hardware whiz (always builds all his own PCs etc), has always sworn by WD drives. So I might go for this instead:

That's because I have so little desk space that I need drives that stand up vertically with a small footprint, so I may have to buy the WD given that it's not clear whether I can use the Hitachi Touro drives vertically on their side - does anyone know?

One thing's for sure, after two Seagate drives going dead parrot on me, the second one being my newest hard drive, I ain't gonna buy Seagates no more, no sirree!

If you get no sound, and there's a white cross on red background against the speaker icon in your Windows 7 system tray (bottom right hand side), with the message "The Audio Service is not running" when you hover your mouse over the speaker icon, there is often a simple solution to this problem.audioWin7

Restarting the audio service usually works to fix the lack of audio sounds in Win 7 (follow this link for instructions on how), just like it usually does in Vista.

A simpler solution may be to just move your volume slider (click the speaker icon then move the slider).

This post shows how to highlight selected text in Adobe Acrobat using just the keyboard, after you select text with the keyboard.

In Adobe Acrobat 8 Professional and other versions of Acrobat, you can highlight text using the Highlight Text tool by selecting the tool, then dragging the cursor over the desired text using the mouse.

Not good enough for me. I don't want to highlight text with the mouse, I want to select text with the keyboard, then use a keyboard shortcut or hotkey to highlight the selected text.

I tried selecting text first with the keyboard (using the Select Tool and the usual Shift keyboard shortcuts), then clicking on the Highlight Text tool, but that didn't work to highlight the selected text.

The secret workaround? After selecting text with the keyboard (by holding down the Shift key then using the arrow keys, End, Home, PageUp, PageDown etc to navigate in the usual way):

  • rightclick the selected text or
  • use the Windows key for the rightclick context menu (usually to the immediate left of the right Ctrl key on the keyboard), or
  • press Shift+F10 (ie while holding down the Shift key press and release the F10 key)

This brings up a context menu which, aha, allows you to  highlight the pre-selected text with the h key. In other words, to highlight text using only the keyboard in a PDF: select text with the keyboard, press the context menu key or Shift+F10, then press h, and voila!

Unfortunately sometimes (not always) the Select tool that lets you select text with the keyboard may vanish or turn into the Hand tool. To get the Select tool back again using the keyboard, try pressing the Esc key, or either press e (quickest, but sometimes inserts the letter e instead!) or press the context menu key or Shift+10 again and then press e. As usual, Ctrl+z is the "undo" hotkey combo, and tapping the Esc key after pressing the e helps if you find it's adding text rather then selecting them or moving the cursor when you try to use the keyboard.

This tip might seem obvious to some but it escaped me for ages, so I thought it was worth blogging this.

Here's how to fix very slow display of text and pics on Powerpoint 2010 / 2007 slides on the screen, whenever you change or even edit slides? A big annoyance - it affects productivity, as sometimes Powerpoint becomes unresponsive and won't refresh, redraw or update the screen at all unless you change slides away and back (only a workaround, and slows things down).

Below is a step by step 'howto' solution to solve this problem of the slow graphics rendering in Powerpoint (others have solved it by changing to the Windows 7 Basic theme, this suggestion has the same effect, on my system at least, and changes the theme for you when you use the shortcut icon concerned to launch Powerpoint):

  1. Rightclick the shortcut icon that you use to start Powerpoint
  2. Choose "Properties" from the menu
  3. Now click the "Compatibility" tab (outlined in red below)

    image
  4. Make sure "Disable desktop composition" is ticked as shown (also outlined in red, above).
  5. Then click "OK".

That's it. Worked for me on a Windows 7 Professional SP1 64-bit desktop, Powerpoint is a zillion times faster now. I hope it works for you too.

Thanks qwerty15!

Background - after a recent Windows update I started getting this problem of Powerpoint is displaying slides too slowly (and it seems a common problem) when moving between or editing slides.

Have you had events appear in your Google Calendar from people that you don't know? Anything from fraudulent requests for money to other stuff like pron. They appear without your accepting the invite, taking up space in your calendar, and you can't delete them without hitting "Decline". A real annoyance.

I recently helped a friend troubleshoot to prevent such spam event invitations showing up in her Google Calendar.

Others have already produced howtos, so I'm posting links to some pages providing the solution to stopping spam invites from appearing in your Google Calendar - the main fix being to set "Automatically add invitations to my calendar" to "No":

  • with screenshot - the best one, as it has a screenshot that also mentions disabling "Show events you have declined" (ie set that to "No"), which may help
  • similar advice

This way you'll still get emails of invitations, which you can choose to accept or decline (or 'maybe'), but the events won't automatically get added to your diary even before you'd chosen to take any of those actions.

But I'd add one more comment. Some people have suggested hitting "Decline" on the invites in question, to stop them from displaying in your Google Calendar, ie get rid of the spam events completely from your calendar.

My reservation about that is that it may send an email back to the spammer, so that they know that your Gmail address is active, and can keep on sending you spam calendar invitations or spam email!

When I set "Automatically add invitations…" to "No" for my friend, doing that immediately stopped the spam event from showing in her Google Calendar. And it didn't send the spammer anything to prompt them to keep pushing spam calendar invites to her!

So I'd recommend trying to disable "Automatically add.." first, before you start hitting "Decline" or "Reject" or the like on the spam event. And only if it doesn't work, consider doing that.

Too many times, when I want to close the current window in Word, I accidentally hit Alt-F5 (instead of Alt-F4) which means it then 'restores', ie reduces the size of all my open Word documents. Every single one of them. I then have to maximise them one by one, individually going to each window first. This is a big annoyance as there is no single command to 'Maximize all windows' in Word, as far as I can find. What a pain.

My solution or workaround, short of finding a way to maximise all Word document windows together at once in one go, is this fix: simply disable the Alt F5 hotkey! Then it does nothing if you hit that combo inadvertently, instead of reducing all your Word windows to tiny unusable ones.

Here's how to disable that hotkey.

  1. In Word, rightclick an empty spot in the toolbar and choose "Customize the Ribbon".
  2. Towards the bottom against "Keyboard shortcuts", click the "Customize" button (outlined in red below):image
  3. Now on the left under Categories, scroll down to highlight "All commands":image
  4. Then click in "Commands" at the top right, and scroll down to find and highlight "App Restore".
  5. Under "Current keys" (outlined in red above) it should now show "Alt+F5".
  6. Click on the line that says "Alt+F5", then click the button (also outlined in red, above) saying "Remove".
  7. Then click the "Close" button.
  8. Then "OK".
  9. That should be it, you should be rid of this nuisance!

UK telecoms regulator Ofcom intends to make calls to 080 and 116 numbers free from all telephones, fixed and mobile, with
03 to be the only non-geographic number range linked to the price of a call to a geographic number (ie an 01/02 number).

But this is only its intention at the moment, it may change its mind. So if you want calls to 080 numbers to be free from your mobile phone, you've got until 28 May to respond to Ofcom's consultation to tell Ofcom that you agree, yes please!

It's been a big bugbear of mine for years, that calling supposedly freefone 0800 phone numbers in the UK is not free on most mobile networks - ie it doesn't come out of your allowance of minutes if you're on a monthly plan, instead you actually get charged extra by the phone company for making 'free' calls from your smartphone or other mobile phone.

Hence the rise and popularity of services like SayNoto0870 and apps like my pal Simon Maddox's 0870 app.

I hope lots of people will respond to Ofcom so that they change the current consumer-unfriendly situation. Please pass it on!

Can't delete folders or files? I kept getting error code 0x80070052 in Windows when trying to delete files, and they just wouldn't delete. Bit of a problem.

However I found that I could permanently delete files (hold down Shift when selecting Delete or pressing the Del key). Ie bypassing the Recycle Bin.

I kicked myself when I realised the answer was simple. Just empty the recycle bin first! (Just rightclick it and choose Empty, for those unfamiliar with the process. It make take a while.) Then you can delete documents, pictures and other files again.image

Nothing to do with file or folder rights or permissions, just as well as I couldn't take ownership of files where I was already the owner!

I just wish the error code was "Recycle Bin too full, please empty it!". That would have been rather more helpful.

Hope my posting this tip saves others some searching.

(If you get error 0x80070052 with USB flash drives apparently the solution there is to move files at the root into an existing folder, or new folder if you can create it.)

After you select text in Word 2007 or Word 2010, a rectangle pops up with options for font type, font size, bold etc etc:

image

This is meant to provide helpful "quick access to formatting tools". In reality, it's always getting in the way of editing, for me and many others.This annoyance that pops up on selecting text drove a friend crazy for years, as she didn't realise that you can turn it off! But if you don't know what that box of formatting menu options is called, you can hardly search for help on the internet to figure out how to disable it…

Well, it's called the 'mini toolbar'. And you can stop it from popping up all the time like a maddening 'son of Clippy'. Here's how.

Word 2010

Go to menu File > Options.

In the General section, under "User Interface Options", UNtick "Show Mini Toolbar on selection".

image

Then click OK, and that's it!

Word 2007

Go to Word Options (which you get to via the Office symbol top left).

In the Popular section, under "Top options for working with Word", UNtick "Show Mini Toolbar on selection" and click OK. And that's it!

After looking for ages for a good free Venn diagram creator, to generate Venn diagrams (set diagrams or Euler diagrams) automatically, I finally found an excellent online tool generously made available by the fab Chris Seidel, which will let you generate a Venn diagram for (as the links below say):
  • 2 or 3 lists ie sets of items for whom you want the logical relationships diagrammed (common items, intersections etc), or
  • 4 lists ie when you have 4 sets of items to diagram.
image
You just paste in your lists of items, one list per column, click "Generate List" and it takes seconds for a nice diagram and tables to be produced. (You'll see there are options to have the diagram in colour or not, etc.)
You can then save the resulting webpage and diagrams and edit the tables etc as you wish. Perfect for my needs! (no, not set theory - just creating good visualisations to explain things more clearly. Picture worth 1000 words & all that). Here's a screenshot of an example:
image
Just one warning and 3 wishlist suggestions for improvement.
The thing to watch is that the lists of items you paste into the columns are separated by spaces rather than new lines or carriage returns. In other words, if you paste in "A word Another word" in one column, it will treat that as a list of 4 items, not 2. A workaround is to get rid of spaces for the same multiword item, ie paste in "Aword Anotherword" instead (but ensure you make the same changes in each list, if the same multi-word item appears in more than one list that you paste in).
The 3 suggestions are:
  1. if you insert a long list name, it gets cut off in the diagram, so make sure your list names are short, say under 10 characters each (just experiment by trying to generate another Venn diagram with a different list name or title, if you find a name is cut off). It would be good if longer names showed up in full.
  2. The helpful table below the diagram is usually labelled something like a(1), b(1), c(0) etc. However, in the generated diagram itself, the labels are 1, 0, etc. It would be preferable if the diagram labels were a, b, c etc instead (or, even better, a(1), b(1), c(0) etc, so it's easier to match up the diagram with the table - otherwise, sometimes it's impossible to match them up except by comparing against the original lists
  3. Finally, the Venn diagram produced would be even better if the list names (shown in red) were shown in the same colours as the different coloured lines that are used to draw boundaries round each list.

Other options?

I've not found anything better, myself. Other online options I've investigated make you work out or draw the common areas manually, or don't have any Venn diagram options at all. If anyone has suggestions do let me know.
While another Venn diagram generator, the Applet For Drawing 3 Set Area-Proportional Venn Diagrams, looks to be not bad, I couldn't get it to work - and you have to feed it exactly 3 lists, no more no less.
Other free open source Venn diagram creation tools I've found, but not yet tested, are:
VennMaster
VennDiagram (downloadable for Windows, Linux and Mac; with article and manual)
Venn Diagrams
If I get a chance to try them I'll of course post my comments.

If your Canon multi-function scanner has suddenly stopped working and won't scan, and you're troubleshooting error messages like "Unable to open TWAIN source", "Cannot open TWAIN source", "Source initialization failed" on trying to scan, here's an easy solution to the problem that's worth trying.

I've not tried it on other i-Sensys MF4100 imageClass series devices, like MF4120 or MF4140, but it worked like a charm on my MF4150. In my case the scanner function on my Canon i-Sensys MF4150 LaserBase laser multifunction printer, copier, scanner and fax suddenly started playing up and it wouldn't scan anything, whatever application I tried to use, even though the printer and copier worked fine.

The MF Toolbox app appeared but, although previously it would automatically scan to PDF, nothing happened after that, no matter what buttons I clicked. Similarly with other scanning apps I tried, like Abbyy Finereader - I just got error messages.

I thought I'd have to reinstall the drivers, but on searching I found a great solution from Jeff Widmer which worked instantly - no rebooting, no unplugging etc! I'm posting it here, with slightly quicker steps.

So here's the step by step on how to get the scanner on your Canon MF4100 series multi-function device working again, for Windows 7 but you could try it for Vista and see (for techies: you just need to add a TWAIN folder's path to PATH):

  1. Open Windows Explorer or Computer, and navigate to
    C:\Windows\twain_32.
  2. Inside the twain_32 there should be another folder, open that folder too (in my case it's named "MF4100", yours may have a different name eg MF4120).
  3. Now hold down the Alt key and tap d. This changes and highlights what's in the Windows Explorer address bar.

    image
  4. Just press Ctrl-c (hold down Ctrl, tap c) to copy that highlighted address line to your clipboard (or if you prefer the mouse, rightclick on that address and copy it in the usual way).
  5. Now go to your System Properties:
    1. The fastest way is to click the Windows Start icon bottom left, type in the search box (without the quotes) "sysdm.cpl" and hit Enter or click the Search icon.
    2. The slower way is to rightclick the Computer icon on your desktop, choose Properties, then on the left click Advanced System Settings.
  6. Make sure you're in the Advanced tab by clicking on "Advanced" at the top if necessary.
  7. At the bottom of the Advanced tab, click the "Environment Variables" button.

    image
  8. In the box that pops up, in the top half (under "User variables"), check under the first column, Variable, and find the variable named "PATH".

    image
  9. Either doubleclick on the PATH line, or single click on it then click Edit. You should get something like this:

    image
  10. You'll see the "Variable value" box usually has a long line of text already in there, highlighted. Be careful NOT to delete anything in that line (click Cancel and try again, if you delete anything by accident). Instead, go to the very end of that line (you can click into the box, then use the arrow keys to go right to the end, or just hit the right arrow key once without clicking anything and you'll be there).
  11. Now at the end of that box, type in a semicolon ie ;
    Then paste in (Ctrl v) what you copied in step 4 above. No need to add any spaces anywhere, just the semicolon and the copied stuff. Here's what mine looked like after that:

    image
  12. Then OK everything. In my case, my scanner immediately started working again, even without a reboot!

If that didn't work, you may need to try reinstalling the drivers. In the case of my MF4150 you have to install the drivers while the device is NOT plugged in to the computer via USB (or dire things may happen and the whole device may not work), but in other cases you can just plug it in, so you have been warned! For the MF4150 you'd unplug the USB cable from the printer/scanner, uninstall the device in Device Manager, reinstall the drivers from the CD (trying to download the latest ones from Canon's site first) and then plug in the USB cable again. Here are Microsoft's instructions on installing/uninstalling drivers for scanners.

I also found a very long thread on (different) fixes for the Canon MP Navigator, which you could try if you've no luck with any of the above - but with Jeff Widmer's fix I didn't need to!

This post is on how to make Firefox load and display all webpages in all tabs automatically when you first open Firefox. Lately it just loads pages in a few tabs (3 max), but pages in all other tabs are blank with no content visible, and the status bar (visible if you use the indispensable Status4Evar add-on) shows "Stopped" at the bottom left.

Other tabs won't display anything but blank until you actually click on the tab for the page. It's very tedious to have to click for each page individually. I save webpages in tabs because I want to use them, and I can't use them if they're invisible!

The quick answer: try Firefox options, then Tab Mix Plus Options, then Session Manager options (if you use either of those extensions), and if all else fails, install the Load Tabs Progressively add-on and change its options, which is what finally worked for me.

Scroll down for full explanations and screenshots.

Background

Many people only want saved startup tabs in Firefox to load when you click on tab, so that Firefox starts up faster. But, like this blogger and others, I want the opposite.

I have a reasonably fast computer with decent amounts of memory. As I use zillions of tabs, it's too time-consuming to have to click on one tab, wait, click on the next tab, etc. I always set my Windows computer to start all my main applications and documents automatically, so I can switch on my computer, go have breakfast or at least coffee, and when I get back to my computer it's all up and ready for me. I want browsers to do this too: I want all tabs to load and display on launching Firefox while I go do something else, and I agree that not allowing this is plain bad usability (though taking away individual users' choice of which option they want is worse).

I wasted too much time trying to troubleshoot and fiddling round with about:config till I found this page explaining that this annoyance is in fact a 'feature' which was introduced in recent versions of Firefox (13 onwards I think).

The current default setting is a pain when you have lots of tabs and have to click each one separately. The point of setting Firefox to launch with a set of tabs is because you want to use them all.

As a workaround, I'd been using 'Reload all tabs' to make all the webpages visible (rightclick on a tab heading for the menu that allows that, if you have TabMixPlus).

General setting

The suggested solution, to force all pages in all tabs load and display when Firefox opens, was to UNtick the 'Don't load tabs until selected' box and OK.

In my version of Firefox (Firefox 15) it's in the Tabs tab of Options (menu Tools, then Options, then Tabs), in others it might be in the General tab.

image

Like so:

image

However, that didn't work for me even after restarting Firefox. There are other options which may need to be set, so try those too.

If you use TabMixPlus

The same link suggested that if you use Tab Mix Plus (TMP) (also an essential extension, in my view), you need to go to TMP Options > Session > Restore and check the "Reload all tabs" checkbox.

If you use Session Manager

As I use Session Manager (which manages loads of sessions with finer control than TMP's session manager), I had no such option, so I went to Session Manager options.

Under General > Saving & Restoring, I UNticked "Restore tabs on demand" (and OK or Apply), to try to get tabs to load automatically without having to "demand" each one individually.

image

If all else fails

Unfortunately, none of the above worked for me - UNticking "Don't load tabs until selected" and the like did not change anything. Only 3 tabs ever loaded automatically when I started Firefox.

Therefore, I had to install an extra extension - Load Tabs Progressively. This works, but I'd recommend some tweaks.

Once you've installed it and restarted Firefox, go to Tools > Add-ons and find Load Tabs Progressively. Click its Options. Change "Maximum number of concurrent loading tabs" to 0 and "Maximum number of loaded tabs" to -1. Then OK.

image

Otherwise, it will load only up to a maximum number of tabs, and only a certain number at a time. If like me you have tons of tabs and just want them all to load while you do something else, you'd want it to load however many tabs you have, ideally all in one go (in my case!).

This excellent extension, as the name suggests, opens each of your saved session tabs progressively, one by one, and the settings I've recommended will get it to open all your saved session tabs no matter how many, and whether using TabMixPlus or SessionManager.

Some websites, like BBC iPlayer, won't work on your Google / Asus Nexus 7. This post gives step by step instructions for beginners on how to get Flash on your Nexus 7 so you can watch or listen to BBC iPlayer TV or radio, and play videos or music on other websites that require Flash like Demand Five or 4od (the ITV Player app does work on the Nexus 7 but the iPlayer app isn't compatible yet).

The tips below represent the easiest solution I've found to add or enable Flash quickly on your Nexus 7, without having to "root" your device (as eg this post suggests) or take any other more complicated steps, thanks to this helpful post and others I found. (There's a risk that rooting may void your warranty.) I didn't need to install an older file Flash apk then update it to a newer one as mentioned here, it just worked with one file, the latest one.

You'll also then need to install and use a compatible browser, as the Google Chrome browser that's provided as standard with the Nexus 7 won't play Flash movies or music etc, even after you've installed Flash. I also explain how to install and use some alternative browsers, below. The problem and background are at the very end, I imagine readers will want the howto first!

How to install Flash on the Nexus 7 - the best way!

So here's the best workaround to solve the problem of Flash not working on the Nexus 7. (It's not really troubleshooting or fixing a bug, it's a workaround - for a situation that was deliberately intended by product suppliers.)

The Nexus 7 is set up as standard to let users install apps only via the Google Play Store. If you want to install an app like the Flash Player using an app installation file that you've dwnloaded, it won't let you do that - unless you change a default setting.

So we'll change that setting first, then download the Flash installation file, then install it on the device direct from the file- aka "sideloading". (In Windows, files to install programs / applications usually end with .exe or .msi - in Android, the operating system used by the Nexus 7, they end with .apk).

  1. (Optional, but may make life easier)  On your Nexus s7, tap the Google Play store icon (the shopping bag icon in your Favorites tray):

    playIconSearch (magnifying glass icon) to find and install a file manager app like ES File Explorer File Manager, Astro File Manager or File Manager HD.

    (For beginners - if you view this blog post in the standard Chrome browser on your Nexus 7, tapping the links above will take you straight there, and you can then tap the Install button to install the app.)
  2. Go to the Settings on your Nexus 7 - ie swipe down the notification shade from the top of the screen, and tap the Settings icon, outlined in red blow.

    notificationShadeSettingsIcon
  3. In the PERSONAL section, tap the word "Security":

    settingsSecurityOutlined
  4. In the Security settings screen, under the DEVICE ADMINISTRATION SECTION tick "Unknown Sources" (this is to let you install an app from a file on your Nexus 7 - otherwise, it just won't let you). Tap OK to confirm you really want to change this setting:

    securityUnknownSources
  5. Now tap open a browser on your Nexus 7, it's easiest to use the Chrome browser that's provided as standard:

    chrome
  6. In your Nexus 7 browser, download the Adobe Flash Player app installation file by tapping this link (the link just given is the direct link to the file that's attached to the bottom of this helpful forum post - if tapping the direct installation file link in your browser doesn't work, you could try going to that forum post and then tapping on the com.adobe.flashplayer-2.apk link from there). A message should flash up very briefly on screen about the download.

    Note: here are some other links from which you may be able to download that apk file, though I've not tried them myself.
  7. Now, find the downloaded apk file on your Nexus 7 and tap it to install Flash. There are two ways:
    1. Swipe down from the top of the screen to open your notification shade, then tap on the com.adobe.flashplayer-2.apk  "Download complete" notification, and tap to confirm the installation:

      notificationDownloaded
      OR
    2. Open the file manager you installed in step 1, browse to the Download folder (a sub-folder of the "sdcard" folder), then tap on the com.adobe.flashplayer-2.apk file and confirm the installation. Here's some screenshots using ES File Explorer:
      downloadFolder
      apkInFolder
  8. Now go back to the Security settings to UNtick the "Unknown sources" setting again, see steps 2 to 2, for security. Whenever you want to install an app from an apk file in future, you can just enable that setting again, install the app, then disable it after installation.)
  9. Note: if tapping the downloaded apk file in step 7 didn't work, try installing an app installer like Fast Installer, then tapping the apk file again. But it should work.

How to play media from Flash sites on the Nexus 7 - use browsers that support Flash!

To actually view Flash sites after you've installed Flash on your Nexus 7, the supplied Chrome browser won't work. That's the way it is, and Google won't be supporting Flash in its Android Chrome browser.

So you have to install a third party browser, and use that in order to view iPlayer or other sites that require Flash.

2 browsers I've tried so far work: Firefox Alpha (Mozilla Aurora) and xScope (free and paid) - hat tip. (Again, those links should take you direct to the installation pages where you can tap to install them.)

But be warned - these are all workarounds, Flash is not officially supported on Android Jelly Bean (the Nexus 7's operating system), so you need to be prepared for random crashes when browsing Flash sites, having to close and restart your browser etc - especially if you try to go to full screen mode (just resizing the page is safest), or leave the page after you've started playing the media, or even just try to pause a video.

Also, different browsers seem to play differently on different sites. So if your favourite Flash site doesn't work well with eg Firefox Beta, try Aurora or XScope etc instead. So far, iPlayer generally works well on Aurora. But different sites eg Demand Five  or 4od may be better in another browser - you just need to try them out (bearing in mind that going full screen may crash the browser, although again iPlayer in Aurora seems relatively OK).

How to use Mozilla Firefox Beta to view Flash sites

Firefox "proper" won't install from the Play Store on the Nexus 7 just yet.

But Firefox Beta, which you can install from the Play Store using that link, does work. Don't worry if you installed Firefox Beta before trying to install Flash Player - all this should still work.

I should note first though that Firefox Alpha, Aurora, seems more stable with Flash, so it may be best to use that for viewing Flash sites - I cover Aurora later, it's very similar.

To use Firefox with Flash sites, first you have to check its Settings to make sure Flash is always enabled, then you need to ensure that iPlayer and other sites won't divert you to the mobile "no Flash" version when you try to browse there.

Here are step by step instructions on how to do that:

  1. Open Firefox, go to the Menu (3 vertical squares, top right) and choose Settings - outlined in blue below:

    firefoxDesktopTicked
     
  2. In the Settings, under the CONTENT section, tap Plugins:

    firefoxPlugins
     
  3. Then make sure Enabled OR "Tap to play" is selected (ie NOT "Disabled"), and you can use the Back navigation button to return to the browser.

    What's the difference? "Tap to play" is more secure; if you pick "Enabled" and visit a malicious website it could automatically run Flash and install malware on your device. This may be more likely with desktop computers than portable devices and apparently it has never happened with Android, although malware has been disguised as an Android Flash Player. But still, if you want to play it safe, use "Tap to play" - then, you need to positively tap on the video or audio to play it, but you'd only do that on sites you trust, right..? Personally I went for "Enabled", but it's at your own risk and all that.

    firefoxPlugins2
  4. Highly recommended: in Firefox, browse to the Phony extension's webpage by tapping that link I gave, then tap "Add to Firefox" to install that add-on.
    1. Now, open the Firefox Menu (the 3 vertical squares), and there will be a new Phony item in the list. Tap on the Phony menu item, then under "Select User Agent" tap the word "Default":

      phony1
    2. A list will open up - find "Desktop Firefox", tap on that, then tap "OK".

      phony2
    3. Now go back to the Menu and choose Quit at the end to close Firefox. (That's because I found I had to restart Firefox before Phony would work.) Then re-open Firefox, and browse away on Flash sites!
  5. Alternative: if you use Flash sites only occasionally and don't want to install Phony, before visiting the site you must first go to the Menu and make sure "Request Desktop Site" is ticked (outlined in red below). Then in the same tab of the browser (do NOT open a new tab), browse to BBC iPlayer or another Flash site, and Flash movies or audio should then hopefully play.
    The downside of this is that, without Phony, you must remember to tick "Request Desktop Site") every single time in a tab, before you visit a Flash site in that tab, as it won't automatically "save" that preference.
    Also, on Firefox Beta, before installing Phony and setting it to "Desktop Firefox" I couldn't get BBC iPlayer radio shows (listen again) to play at all, although it would play iPlayer television programmes.
    Finally, with BBC iPlayer at least, even after ticking "Request Desktop Site" you may have to keep trying to reload the page or going to it again via a link on a search engine results page, as sometimes it still diverts you to the annoying "not supported" page shown towards the end of this post. This doesn't happen with Phony. Which is why I highly recommend using it!

    firefoxDesktopTicked 
  6. Note: sometimes, on some sites, you will still have to tap on the video or audio in order to kickstart Flash, even if you've selected "Enabled" instead of "Tap to play".
  7. With iPlayer TV: don't use the "popup" icon (the two overlapping rectangles) as that won't work - instead, use the Full screen icon, outlined in red below:

    iPlayericons
  8. Feature request: if only Mozilla would provide a setting for Firefox mobile to permanently request desktop sites so a third party add-on wasn't needed! (and in portrait view moved the Menu button to the navigation bar at the bottom - I keep hitting tabs inadvertently when trying to get to the Menu in portrait orientation!)
  9. Full screen, and avoiding crashes:  updated: be patient and don't tap on the video before it has finished loading and shows the play arrow on the video itself, otherwise it may crash. Also remember, it's best generally to avoid full screen mode. Full screen may work sometimes with iPlayer, but with other UK TV sites like 4od etc, it may crash the browser, and you'll have to close it and restart it again! Workaround - the best fix to get close to full screen, from combining tips and tricks from a couple of forum postings, is this:
    1. on your Nexus 7, download and install the free Full Screen add-on
    2. when you need full screen, activate the add-on through the Firefox menu (you may need to scroll down the menu items list to find "Full screen")
    3. start playing the video, and then double tap on the video to enlarge it almost to full screen
    4. to come out of full screen, press and hold (aka "long press") on the webpage and choose "Exit" out of full screen.

How to use xScope for Flash sites

xScope (free and paid versions) is another browser option which needs fewer steps than Firefox to set up and use.

Once you've installed and opened xScope, you just need to check its Settings to make sure Flash is enabled. Here's how:

  1. Go to xScope's Settings by tapping the menu icon (3 vertical squares, top right) then tap Settings:

    xscopeMenu
  2. On the xScope Settings page, in the "WEB PAGE" section, I chose to tick "Auto load flash" (but bear in mind the note under the Firefox Beta section above about the risks of auto-loading flash if you visit a malicious website - you have been warned!):

    xscopeFlashSetting
  3. You  can now visit BBC iPlayer and other Flash-using sites via xScope, and Flash should just work. But note that, sometimes, as with Firefox, you do still have to tap on the video or audio in order to kickstart Flash. Or, of course, if you haven't set Flash to auto-load. And remember to avoid full screen mode
  4. One more precaution: it might be best to stop auto-update for xScope, in case a future version of the browser comes out that disables Flash. (This is a real risk - the Dolphin browser for example no longer supports Flash, whereas an earlier version of it does, though on some pages it may crash on switching to full screen). So here's how to disable the auto-update:
    1. Open the Google Play store on your Nexus 7 (shopping bag icon, see step 1), then get to your lists of installed apps by tapping the down arrow icon at the top:

      playApps
    2. Now in the apps list, tap on the name of the app you need to change auto-update for, in this case xScope:

      playXscope
    3. Finally, on the xScope screen in the Play store, UNtick "Allow Automatic Updating". (You can retick it again if you're absolutely sure the developer won't disable Flash support in a future release!):

      xScopeAutoUpdating

 

What about other browsers, do they support Flash?

You can also use Firefox Alpha (Aurora) - just download its apk file from this page (the one that worked for me was called fennec-16.0a2.en-US.android-arm.apk - version 14 didn't work, for instance). Then install it in the same way as you installed Adobe Flash Player above, making sure you tick the "Unknown sources" security setting first, check the Flash setting, and install and set the Phony add-on as with Firefox Beta (or check "Request Desktop Site" is ticked every time before you visit a Flash site).

Here are screenshots for Firefox Aurora, it's much the same as with Beta, but it's your choice as to "Tap to play" or "Enabled", and don't forget you need to tick Request Desktop Site every single time:

auroraMenu

auroraPlugins1

auroraPlugins2

An earlier version of the Dolphin browser has been mentioned above as working, and I've checked it works with iPlayer radio  - but it crashes if you try to go to full screen with iPlayer video or YouTube, and presumably other sites too. (If you already have Dolphin you should uninstall it first before installing that earlier version - go to the same screen for Dolphin as for automatic updating, above, and tap Uninstall.)

Maxthon was reported to work but for me unfortunately the HD tablet version kept crashing on trying to pause a video, or just trying to access the menu or settings. The mobile (non-HD) version of Maxthon did work, and you can also in Maxthon enable Flash automatically (via its menu - bottom right navigation bar, choose Options, Browser settings, change "Flash on demand" to "Always on") - similar to what I've shown for the browsers above. Otherwise, you'd have to tap on a Flash video or audio in order to play it.

Tip: with Maxthon mobile in landscape view, you can't see the address bar in which to type a URL - you have to swipe down the grey horizontal lines in the curve, kinda like a tab, outlined in red below:maxthonHoriz1Then voila you can see the address bar!:

maxthonHoriz2

Unfortunately I couldn't get Flash to work in either Opera Mini or Opera Mobile.

While Puffin has been said to work, I personally wouldn't use it as (1) they've enabled Flash on the free version only for the London Olympics period, so Flash may stop working in it after that, and (2) BBC iPlayer radio works in Puffin, but if I try iPlayer TV, it won't work as the site then seems to think I'm not in the UK (whereas I am):

puffinNoGo

The Boat browser also reportedly works (in the Settings check under Page content settings, Enable flash/plug-ins first) - but for me it always crashed after starting to play iPlayer video.

Sleipnir wouldn't work for me at all, even with all plug-ins enabled.

If anyone knows of other browsers that reliably support Flash on the Nexus 7, please let me know.

The problem - BBC iPlayer and other Flash sites don't work on Nexus 7 out of the box!

Your shiny new Google / Asus Nexus 7 unfortunately won't play BBC iPlayer video or audio, or indeed media on other websites that use Adobe Flash. You may get screens like these:

"Your phone does not support BBC iPlayer":

iPlayerNo

Or you may get, "You need to install Flash":

chromeNeedsFlash

But… if you then try to install Flash Player from the Play Store, you may get… "Your device isn't compatible with this version"!:

playFlashNotCompatible

Background to the Nexus 7 Flash issue

A big disappointment with Google's Nexus 7 Android tablet is this lack of support for Flash, which is used by BBC iPlayer and many other websites for displaying videos or playing music or other audio.

Adobe recently withdrew support for Flash on Android devices and other mobile browsers, although this move was presaged in late 2011. If you try to install Adobe's Flash Player browser plugin from the Google Play Store to your Nexus 7, it won't let you.

While that's really down to Adobe, not Google, it's still a pity that Google didn't provide at least some support for Flash in its Chrome browser in the Nexus 7, given that the tablet is being heavily publicised as a media player - that omission is in my view a Google Gaffe. Indeed, a friend told me that being able to watch or listen to BBC iPlayer TV or radio ("listen again") in bed was a major reason why he'd ordered a Nexus 7, and I suspect the same goes for many other Nexus 7 buyers.

Adobe envisaged that the ultimate solution to this issue would be for websites to eventually move to providing their media using the open HTML5 standard, instead of using Flash.

Unfortunately, that's going to take some time - there are real problems today because many, if not most, websites on which people generally want to view videos or audio don't use HTML 5, but still rely on Flash. So users have been left in the lurch, until sites update their content to migrate to using HTML 5.

The Google / Asus Nexus 7 tablet is far more than just an Amazon Kindle Fire competitor. It works well with a Bluetooth keyboard too, making it an ideal computing device for working on the move if you're a business user who finds a laptop or even iPad too heavy to be truly portable (eg if you have a bad back). See the end of this post for the weight comparisons.

How to pair the Nexus 7 with a Bluetooth keyboard

First here's a video demo of using Bluetooth keyboard with Google Drive on Nexus 7; instructions on pairing are below:

Below are step by step instructions on how to pair the Nexus 7 with a Bluetooth keyboard  - in my case, an ancient iGo Stowaway Ultra Slim Think Outside keyboard, sadly now discontinued - originally bought for use with the Nokia N95 smartphone, it's that old!

  1. Make the keyboard discoverable - with the Stowaway, you hold down at the same time the Ctrl, left Fn (blue) and right Fn (green) keys. A green light will flash slowly above the T button to confirm it's working.
  2. On the Nexus 7 go into the Settings (swipe down from the top and tap the Settings icon):

    settingsIcon
  3. In the Settings screen, in the "Wireless and Networks" section, slide the Bluetooth switch from "OFF" to "ON".

    settings
  4. You'll see a blue On button against "Bluetooth", as well as the Bluetooth icon showing at the top right of the screen. Now, tap on the word "Bluetooth" (in the list on the left under "Wireless and Networks"), and you'll get the following screen. Tap "Search for Devices" at the top right.

    searchForDevices
  5. Under "Available devices", your keyboard's name should appear. Tap its name.
  6. The Nexus 7 should pop up a message with a 4-digit numeric code to enter on your keyboard.
  7. On your keyboard, enter the 4-digit code given, and hit the Enter key.
  8. They should now be paired, and you should be able to use the keyboard with Nexus 7 apps. Type away!

    keyboardBluetooth
  9. Tip: get a Bluetooth widget like the free Bluetooth OnOff so you can turn Bluetooth on and off quickly from your Home screen with one tap. (Obviously turning it off will save power when you're not using Bluetooth).

Why buy a Nexus 7 for portable working?

Just compare these weights:

  1. Nexus 7 (just 340 g) + iGo Stowaway Ultra Slim full-sized folding Bluetooth keyboard (160 g)
    = only 500 g.
  2. iPad 2 = 590 g - ie heavier than the above two items combined. Unfortunately the new iPad is even heavier, at 652 g.
  3. Microsoft's planned Surface tablet with built-in keyboard = 676 g for the lighter version (from the specifications).

So, it's the Nexus 7 for me, until someone produces a modern clamshell Psion 5mx with wi-fi and colour screen - my #1 wishlist item, it's still the best portable computer of all time, only 354 g including full touch-typable keyboard and batteries, and decent sized screen with zoom!

I strongly feel there's still a massive gap in the market for light, small form factor, full computers (my biggest gadget beef).

Weight, the first thing I check in specs, rarely gets mentioned in reviews, but it's an issue for some women, youngsters, and people with back problems who just can't physically carry around laptops, notebooks or even netbooks.

So it's heartening that it's not just me - the techie likes of certain Slashdot readers also consider size/weight first when buying a portable computer.

My brand new Google / Asus Nexus 7 was faulty (or rather, the charging unit or cable was).

Google's Nexus 7 support phone number for UK customers, for ease of reference is:
0800 328 6081

Also see:

Google Goodness: it's an 0800 number, free to call from a landline (though NOT from a mobile, still a major issue in the UK, and a big wishlist item for me). Thank you, Google - that beats premium rate 0870 or non-geographic (and still chargeable from a mobile) 0845 numbers!

Google Gaffe: Google may not have planned ahead enough for the volume of calls. I've had to call a couple of times now, and each time I had to wait in a queue for 45 minutes to an hour before I could talk to someone. Just as well it was a freefone number!

Google Gaffe 2: the support staff don't seem to have full knowledge or training about the Nexus 7, or remits across the spectrum of support issue - so you might get "It's another team that deals with that aspect", or "I didn't know the Nexus 7 Gmail app displayed emails against a grey background". I also got different (and conflicting) information on different occasions from different people. Less good. At least they're friendly and try to be helpful, without being over-familiar, long-winded or annoying (ahem Three!).

The good probably outweighs the gaffes here. Given that most support helplines charge you a fortune for the privilege of trying to sort out a problem with their product or service, Google's provision of an 0800 support number was enough to make me forgive the other issues.

So - it's +1 to Google for Nexus 7 support, overall. So far. I reserve final judgement until my replacement unit and return are fully sorted out!
