The above error stops me from using FF. I have removed it and reinstalled it twice. Same problem. After two years of FF use I had to to back to IE8. When I checked on the problem several weeks ago I found 161 people had the same problem. I have not been able to delete the FF reference in the registry. Running XP Pro. My laptop without any FF updates works fine.

Do a clean (re-)install:

  • Download a fresh Firefox copy and save the file to the desktop.
  • http://www.mozilla.com/firefox/all.html
  • Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
  • Don't remove personal data if you uninstall the current version.
  • It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

You do not need to create a new profile, that is not necessary for this issue

Your bookmarks and other profile data are stored elsewhere (not in the Firefox program folder) and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.
