Try the Firefox Safe Mode to see how it works there. The 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 the Firefox 4.0+ Safe Mode by holding the Shift key when you use the Firefox desktop or Start menu shortcut.
• Or use the Help menu item and click on the Restart with Add-ons Disabled... menu item while Firefox is running.

Don't select anything right now, just use "'Start in Safe Mode" To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shift key) to open it again. If it is good in the 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.

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

Hi,

I am having the same problem. Firefox updated earlier today to 18.0 and since then it keeps freezing when I visit Facebook and I have to force quit it. I'm running Snow Leopard (10.6.8).

I tried starting Firefox in safe mode, and disabling all add-ons. I even went to "Troubleshooting Information" and reset Firefox to fix this problem, and nothing works.

Maybe the problem is with compatibility between Snow Leopard and the new update. I hope there is a fix to that soon.

I have this same problem and I'm running Mountain Lion 10.8.2. Facebook seems to work fine if I navigate to someone's page directly, but freezes firefox if I try to go to the news feed. As with the other posters, I've tried starting firefox in safe mode but it has no effect.

This issue seems exactly the same as the one posted here about Firefox 17: http://support.mozilla.org/en-US/questions/945235

If you go to about:crashes, can you give me the crash IDs? (they start with bp-). We are investigating a crash on Facebook, and this might be it.

I have been having the same problem since updating to 18.0, and I am also using Snow Leopard (10.6.8). Here are my most recent crash reports, all of which I can trace to Facebook. However, I did not submit them all as that gets tedious.

(I think the last one listed is the one I actually submitted.)

Or maybe these are the right numbers? They changed when I clicked on them (and hopefully the returns will carry in this post).

Looks like a problem with one of the plugins.

• https://support.mozilla.org/kb/Troubleshooting+plugins

Solution for this problem is as follows:

Step 1: Go to about:config

Step 2: Click on "I'll be careful, I promise" when it tells you this might void your warranty.

Step 3: In the search box, type "dom.max_script_run_time"

Step 4: Double click "dom.max_script_run_time" and change the value from 10 to 25

That should fix the problem.

I think the problem is with one (or many) of the plug-ins.

I have this same problem, just gets stuck "running ball" in the News Feed. I have to Force Quit to resolve. It doesn't happen on individual pages.

I've tried the "dom.max_script_run_time" value change and no difference. Also does it when running in safe mode.

I came back to Firefox 6 months ago from Chrome, but this issue is a near-deal-breaker for me as I am on Facebook all the time for both personal use, and managing Client pages.

OSX 10.8.2, Firefox 18

I have repeatedly tried disabling all my plugins (which gets Facebook to load) and then enabling them one by one. I check Facebook after each one is enabled, and it still works. Even after all ten plugins are reloaded. Then I will leave the comp for some time, come back and restart Firefox... and there is the whirly ball of doom again. Here are my most recent crash reports:

53B5DCFC-C3CE-4DEF-AF27-C270821A16B2 1/14/134:34 PM (bp-c5df4531-9def-4bf0-bcf2-e8ec52130115 after I click on it)

Also, here are a list of my plugins, maybe we can narrow down the offending plugin somehow?

Silverlight Plug-In

QuickTime Plug-in 7.6.6

Java Applet Plug-in

Shockwave Flash

iPhotoPhotocast

Google Earth Plug-in

Microsoft Office Live Plug-in

AmazonMP3DownloaderPlugin

Adobe Acrobat NPAPI Plug-in, Version 10.1.3

Unity Player

And now it is happening on Kongregate.com, when I tried to play a Unity game. So that makes me think Unity is the problem. Anyone else have other sites causing the same issue?

And the dom.max_script_run_time fix helped nothing.

Can you install Firefox nightly and tell me if Unity still crashes? http://nightly.mozilla.org/ it should be fixed there.

Seemed to work fine, though I found out another user on my computer was able to get it to work last night by removing and reinstalling Unity. Haven't had the crash issue yet today, as it seems to come and go.

Somehow I made a duplicate of this question. Heres the other forum: https://support.mozilla.org/en-US/questions/946538?page=2#answer-399103

Ok... I found a temporarily fix... go to facebook.com, then click the (X) button in the bar to make the page stop loading. it should only be half loaded... if firefox locks up, you waited too long. Click on your name in the corner. Then when that loads, click home, next to your name!!!!! There is your news feed! Hope this works... It worked for me. Enjoy!!!

The latest Firefox update (which I got today) seems to have cured this. Thank you Mozilla!
