Your crash report shows cause of crash as SIGSEGV. One of them mentioned Shockwave Flash. Go to their web site and see if there is an upgrade or try to download it again.

If there is still a problem;

Try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that turns off some settings and disables most add-ons (extensions and themes).

(If you're using an added theme, switch to the Default theme.)

If Firefox is open, you can restart in Firefox Safe Mode from the Help menu by clicking on the Restart with Add-ons Disabled... menu item:


If Firefox is not running, you can start Firefox in Safe Mode as follows:

• On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.
• On Mac: Hold the option key while starting Firefox.
• On Linux: Quit Firefox, go to your Terminal and run firefox -safe-mode
  (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)

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 to find the cause.

To exit 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 others with the same problem.

Thank you.

The problem will not be solved by updating Flash. You may check with

• The firefox plugin check http://www.mozilla.org/plugincheck/
  That is sometimes a bit flakey and has Work In Progress, to improve it.
• Or http://www.adobe.com/software/flash/about/

Both should confirm that your FlashPlayer is up to date. Adobe does not fully support Linux and the versions of Flash Player will not match those of Windows.

Each crash report has a different signature, and I will not pretend to understand them.

Try in Firefox's safe mode and with all plugins disabled. That may help and prevent crashes, or it may at least result in a consistent Crash Signature that may be more understandable to me. Should safe mode alone happen to work then next try instead just running with Hardware acceleration disabled.

flash player are up to date.crashes in safe mode also.

Please include two or three of the new CrashIDs from the crashes in safe mode with all plugins disabled.

Also try the Firefox reset, but not that removes your extensions, so you may wish to bookmark the homesites of any extensions before doing the reset.
