Try to run the Firefox program once as Administrator (right-click firefox.exe: Run as Administrator).
If that doesn't solve the problem then remove the Firefox program folder (C:\Program Files\Mozilla Firefox\) to do a clean reinstall.

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

Uninstall your current Firefox version, if possible.

  • Do NOT remove personal data when you uninstall the current version or you lose your bookmarks and other data in the profile folder.

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

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.
