I had firefox4.0 installed in my PC. There was a glitch in the browser so I uninstalled it and now when I am trying to re-install any version of firefox, I am unable to.

This is the message that I see when I try installing any version of Firefox: Your computer must be restarted to complete a previous uninstall of Firefox. Do you want to reboot now?

If there are problems with updating then best is to download the full version and uninstall the currently installed version.

Download a fresh Firefox copy and save the file to the desktop.

  • Uninstall your current Firefox version.
  • Do not remove personal data when you uninstall the current version.

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

  • 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.

Your bookmarks and other profile data are stored elsewhere in the Firefox Profile 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.
