  1. Delete the files and folders in the Firefox installation directory, default location is C:\Program Files\Mozilla Firefox\
  2. Re-install Firefox

This method will not remove your Firefox user data such as bookmarks and passwords, those are stored elsewhere in your profile folder, and will be used when you re-install Firefox.
