Updated to 4.0 version and when it finished loading I got 4 identical Firefox icons on my desktop. I went back in time on my computer to go back to an order version and Firefox won't open or is very slow to open.

Do a clean (re-)install:

  • Download a fresh Firefox copy and save the file to the desktop.
  • Firefox 4.0: http://www.mozilla.com/firefox/all.html
  • Firefox 3.6.x: http://www.mozilla.com/en-US/firefox/all-older.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.
  • It may not be necessary to create a new profile, so first try if it works with your current profile and if not then create a new profile.

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.
