Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I have Ubuntu 12.10 and it most of times crashes. I've disabled all plugins, resetted firefox, started in safe-mode, but still crashes. It even crashes in safe-mode after firefox reset.

I also did firefox purge via apt-get and re-installed it after cleaning apt-cache (re-download), still crashes...

Sometimes crashes becomes constant, I mean, it crashes right after I click on firefox icon, then I press quit, re-click on firefox icon ONLY, crash!, re-click crash! etc.

I checked /var/log/syslog and dmesg, can't find anything related to firefox or mozilla.

Please advice.

Make sure Firefox isn't running. Then rename ~/.mozilla to something else and see if Firefox still crashes. –  user25656 Feb 13 '13 at 17:30
    
I should run firefox from terminal, and post the results here. There might be something useful in that output. Also, see the options listed in answers for this question here. Try a new firefox profile, for example. –  user76204 Feb 13 '13 at 17:55
    
I deleted my .mozilla folder, deleted apt-get cache, re-installed firefox, nothing changes. When I run it from console, I was looking for something useful too, but nothing at all! No error in console, no anything related to problem in console. –  Vahid Farahmand Feb 14 '13 at 13:42

Try updating your local package index by running apt-get update before you reinstall Firefox. This will make sure you're installing the latest version.

There is a Firefox help page containing several suggestions for debugging Firfox crashes. Here are some of its suggestions:

  • Update Firefox | see above
  • Update Linux and drivers | run a full system upgrade by running apt-get update && apt-get upgrade
  • Check you RAM | on boot, hold shift when GRUB comes up and run a memory test.

apt-get purge does not remove files in /home. It only removes system config files (in addition to whatever apt-get remove removes). So you may want to modify the currently last sentence to something more appropriate. –  user25656 Feb 14 '13 at 2:58
    
I cleared apt-get cache, my Ubuntu is up to date and have no available update package, then re-installed firefox, nothing changes... –  Vahid Farahmand Feb 14 '13 at 13:41
    
I have removed the note entirely. I'm a bit new here. Is my answer considered acceptable or should it have been a comment? –  paraxor Feb 14 '13 at 15:27
