Firefox 21 and 22 freezes computer

Comment from a forum moderator

This thread at present one time had over 200 metoo votes and nearly 7.5k 24k views. So no one is saying there is not a real problem needing addressing.

Some of you may be interested in my (very long explanation) post lower down in this thread link or the short but sharp LINK ~J99

I have the problem that lately Firefox keeps freezing/hanging my computer, making it totally unresponsive, the only fix is a hard reboot. The freeze often occurs just moments after I start the browser and go to a website, which site I visit does not seem to matter. Sometimes it has seemed about to freeze, lagging the cursor, but then catching up and making it.

I've just tried using IE instead, and I have no freezes. But I would very much like to fix this problem and get back to using Firefox.

I updated Firefox from version 21 to the most current 22, no difference. I've also tried updating Flash Player and when that did nothing I disabled all plugins, nothing as well. I've run a full anti-virus scan, so it's likely not a virus. I've also tried reinstalling my Graphic Card drivers, with no result.

The computer is my HTPC and is thusly connected to a 46" TV. I run with 150% DPI scaling in Windows 7 to be able to see text better. Since it's my HTPC I don't use the computer every day, so the most recent driver change I've done was updating my Graphic Card drivers, but if it's connect I can't say since reinstalling the driver again did nothing.

Specs: OS: Windows 7 64-bit Barebone: Shuttle FZ68 CPU: Intel i3 2100 3.10 GHz RAM: 8GB DDR3 GPU: EVGA GeForce GTX 460 768MB

Re: Firefox 21 and 22 freezes computer

Hello,

Try Firefox Safe Mode to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.

(If you're not using it, switch to the Default theme.)

  • You can open Firefox 4.0+ in Safe Mode by holding the Shift key when you open the Firefox desktop or Start menu shortcut.
  • Or open the Help menu and click on the Restart with Add-ons Disabled... menu item while Firefox is running.

Once you get the pop-up, just select "'Start in Safe Mode"

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article for that.

To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.

Thank you.

Hello, FYI

  I try to start firefox (22) in safe mode and the freezing problem is still here.
  The browser freeze when after call to multipart/data form. It seems to be released after a timeout (aprox 30s -1 min).

With aurora 21.0.a2 the problem does not occur, as for other browsers.

Seems like this bug (still unsolved): https://bugzilla.mozilla.org/show_bug.cgi?id=859038 If you have the same problem, consider voting up that bug.

Edit
Comment by a forum moderator. I have put a line through some of the above. That bug and some related bugs are resolved i.e.the known issues seem to have been fixed. There is now no point in voting in those bugs. ~J99

Hello,

Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.

You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).

Then perform these steps:

  • Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
  • In the Firefox options window click the Advanced tab, then select "General".
  • In the settings list, you should find the Use hardware acceleration when available checkbox. Uncheck this checkbox.
  • Now, restart Firefox and see if the problems persist.

Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:

Did this fix your problems? Please report back to us!

Thank you.

Re: Firefox 21 and 22 freezes computer

Ok, I followed your instructions and it made no difference. Thank you for the suggestion. Judging from the comments on the Bugzilla board, this is a very specific bug that is reproducible by many users. It may require a code change and update rather than fiddling on the users' end. Or perhaps there is a bug in the most recent Java version? Firefox runs on Java, yes?

Re: Firefox 21 and 22 freezes computer

Hi NerdyTechie, I think there might be two different problems being discussed in this thread:

(1) Original issue that Firefox freezes Windows after starting the browser;

(2) Second issue that when you resume Windows from "sleep", that Firefox 21 is unresponsive for a long period of time (but other applications are not affected).

Which problem do you have?

For what it's worth, Firefox does not run on Java and you do not need the Java plugin for most sites.

Re: Firefox 21 and 22 freezes computer

Hi Aethyr, could you also undertake these prophylactic steps that address the most common issues with the Flash player plugin. I'm sure you've seen some of it before, but just in case:

(1) Make sure all recorders/downloaders that interact with Flash media are as up-to-date as possible, or disable them.

(2) Disable hardware graphics acceleration in Firefox and in Flash

(A) In Firefox, [as noted in a previous post] un-check the box here and restart:

orange Firefox button (or Tools menu) > Options > Advanced > General > "Use hardware acceleration when available"

(B) In Flash, see this support article from Adobe: http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues

(3) Disable protected mode (Windows Vista/7/8)

See this support article from Adobe under the heading "Last Resort": Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox?

Re: Firefox 21 and 22 freezes computer

Thanks for the prompt reply. I should have included the bug report I was talking about. It's this one: https://bugzilla.mozilla.org/show_bug.cgi?id=859038 If the computer falls asleep with Firefox open, then upon awakening, has a problem refreshing the UI. Clicking the systray a couple of times forces a single refresh but the problem continues. I can quit Firefox normally, choose close all tabs, and when I reopen Firefox I can choose to restore the prior session and everything works fine. This is definitely related to something that is happening when the computer either falls asleep or wakes from sleep.

NerdyTechie,

Your problem is off topic for this thread. Please start a new thread or join a discussion about Firefox being unresponsive after resuming from "sleep".
