Firefox used to work fine, then a few days ago it just stopped. When I try to start it, it comes up with a message that "firefox has stopped working". That message comes up over the box that asks if I want to start in safe mode or reset firefox. when i try to close or cancel that message so I can try starting in safe mode, both sets of messages go away.

if I try to start in safe mode using the shift key, the same thing occurs. The same thing occurred after I uninstalled and reinstalled.

Do a clean reinstall and delete the Firefox program before (re)installing a fresh copy of the current Firefox release.

If possible uninstall your current Firefox version to cleanup the Windows registry and settings in security software.

  • Do NOT remove "personal data" when you uninstall your current Firefox version, because this will remove all profile folders and you lose personal data like bookmarks and passwords including data in profiles created by other Firefox versions.

Remove the Firefox program before installing that newly downloaded copy of the Firefox installer.

  • (32 bit Windows) "C:\Program Files\Mozilla Firefox\"
  • (64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"

Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.

If you keep having problems then also create a new profile.
