Immediately after I double clicked the icon, it immediately showed crash reporter dialog.. I don't even see the browser window to try the safemode.

I uninstalled and resinstalled. Still crashed.

Hello josat2013. The cause of this could be a corrupted user profile in Firefox, which if I remember right is not removed by the uninstaller.

Could you try and see if creating a new profile works? I am going to assume you use Windows 7 for the walkthrough. While on your desktop, click the start menu and write firefox.exe -profilemanager. Unless Firefox crashes while doing this, it should show a small window with the name of the current Firefox profiles on your system, usually it is named #randomcharacters#.default. On the left hand side you should see a button called New Profile, click this and follow the instructions where you specify the name and etc.

After you have finished the instructions you should see that there is a new profile in the list with the name you specified. Highlight this one and choose click on Choose Firefox. If the Firefox window appears without crashing, then the cause is that corrupted profile.

To transfer all your files and settings to the new profile, follow the instructions on this webpage: http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox

Good luck and hope it works out! :)

Hello, can you open firefox in safe mode, by holding down the shift key while starting Firefox ?

if you can open firefox in safe mode, and crashes again

  1. Enter about:crashes in the address bar (that's where you enter your website URL) and press Enter. You should now see a list of submitted crash reports.
  2. Copy the 5 most recent crash ID's that you see in the crash report window and paste them into your response here.

More information and further troubleshooting steps can be found in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.

  • if you can not open firefox in safe mode try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) and check firefox again.

(If works in Windows Safe mode then you have a problem with other software, like security software or maybe a system driver, that is running on your computer).


thank you

I have this problem too. I have to uninstall and reboot every time FF crashes.

That is a problem with the Flash plugin.

You can check for problems with current Flash plugin versions and try these:

  • disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
  • disable protected mode in Flash 11.3 and later
  • disable hardware acceleration in the Flash plugin

Thank you. I completed your suggestions and am still crashing.

When I navigate to Add-ons, I do not see anything named Real Player. Nor do I see this in control panel -- programs.

Thanks so much!

Try to update all plugins.


Check for plugins that need to be updated.

Boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.
