Firefox 18.0.1 often freezes, at random times, since about 31 Jan 2013

2 Feb 2013 Concerns: Firefox 18.0.1 often freezes, at random times, since about 31 Jan 2013 I am using Mozilla Firefox 18.0.1, Windows Vista, PC, Desktop. My Mozilla Firefox freezes since about 31 Jan 2013 at random times quite often, when I do see TV or videos, also with YouTube videos. It freezes especially when I do start TV or a Video, sometimes also it freezes when the video is running for some time. I do use Firefox mostly only for TV and videos, so else I do not see. Some days earlier (26 January 2013), I had installed the upgrade of the new Norton Internet Security 2013. The two Norton add-ons on for Firefox, I have both deactivated. I can get out of the freezing, when I do click to end the Internet connection. After I have waited for about 5 seconds, the Mozilla Firefox browser can be moved again with the cursor. After I click to close the Firefox, and wait for about 5 seconds, the freezing also does end. I did do two Windows restores, one to 1 week ago and the next to 2 weeks ago. After the restore, when I started Mozilla Firefox, it was at first Firefox 17. But to my very bad luck, Firefox started immediately to update to Firefox 18.0.1 I had seen this updating on Help – About Firefox. There were good times, when people could choose themselves which version of Firefox they wanted. After the restore, I had also downloaded the latest Adobe Flashplayer version (about version 11.5), but the freezes have remained the same. Is there a possility to prevent the automatic update of Firefox? So that I could choose which version of Firefox, I do want. When there is a serious bug in Firefox, I could nevertheless use Firefox instead of changing to the Internet Explorer. I know I myself am responsible to prevent hackers from entering my computer. I have read that 80% of users in Germany do not have any Internet Security against hackers at all. My Internet Explorer until now does not freeze.

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.


Further information can be found in the Refresh Firefox - reset add-ons and settings article.

I had same troubles for last 48 hours (Feb 1 and Feb 2), My FireFox would crash 1 second after loading any web page. I removed all Comcast plug-ins, Yahoo toolbar I never used and disabled Java versions 6.0.290 and 6.0.310 platforms...my system (old Windows XP on a HP) is now running FireFox 18.0.1 without issues for 15 minutes and test trying a few web pages.

I also have this problem with version 18.0.1 and it became only a problem in Jan 2013. I am running it in Windows 7 Home Edition and 'pausing' occurs at home (via cable modem) as well at work (university network).

Could it be that version 18.0.1 uses an unusual amount of memory resources over previous versions? If so, how would one check this and what might be a 'work-around'?

Resetting Firefox solved my problem. Tylerdowner - you are the man.

This is not a solution. It is a gun in the mouth. Give us specific solutions, not "throw everything away" palliatives that involve no thought, investigation or effort of any kind on Mozilla's part. 95% of the utility of FF is not FF itself, but addons. After many years of developing that context, throwing it all away to get back a rudimentary 5% is as unacceptable as it is stupid.

DonGately Your dissatisfaction with the solution could have been stated a bit more tactfully rather than just 'trashing' it.

Sorry, but my frustration at being dead in the water for days and getting generic suggestions that don't address the problem goes far beyond my threshold of tact.

I went back to 17.0.1 with the same set of addons and plugins and I'm fully back to being productive again. This suggests a FF bug, not an addon problem.

relative to my comments on Feb 2, deleting FireFox 18.0.1 and re-installing made no difference; installing and going back to 17.0.x made no difference; disabling and removing the identified Add-Ons were FireFox's own self diagnostics indicating those items were "unstable" or "not compatible with FireFix 18.0.1"....I'm happy with the solution I posted if it helps anyone. As for debugging and finding the root cause in the offending lower level application code (I don't have the correct tools for that type of debugging nor am I paid for it).

My sincere apologies to anyone who took my rant as a personal attack. My target is Mozilla collectively not any one individual or anyone that is just trying to help. But my criticism of their standard response stands.
