I've tried going through all the solutions I can find including trying unlock my profile (parent.lock), or create a new profile (profile manager crashes too), opening it in safe mode (it won't - still crashes), running it as administrator (also crashes) and I cannot uninstall it (that crashes too). The Crash Reporter/Manager also crashes and locks up so I cannot submit this issue. I'm at a loss.

Hit CTRL+SHIFT+ESC to bring up Windows Task Manager, go to the Processes tab and look for firefox.exe If you find it, right click it and choose Kill Process.

What I suggest next is to perform a clean installation as follows:

  • Go to Download Firefox 4.0 and download a fresh installation file to the desktop. In this particular case, I'd recommend downloading the file with either IE8 or 9. Choose to save the file to your desktop when you see the prompt.
  • Then go to Add/Remove Programs, scroll down to Mozilla Firefox and remove it, choosing to keep your bookmarks, customizations etc., (don't checkmark the box).
  • Then reboot and delete the folder called Mozilla Firefox at this location: C:\Program Files\Mozilla Firefox
  • Finally run the installation file you downloaded to the desktop earlier.

Your bookmarks, customizations etc., will be retained in a separate folder and will become available again once the reinstallation completes.

If you prefer to go back to the previous secure version which is 3.6.16, use this link instead: Download Firefox v3.6.16 Otherwise the procedure is the same.
