  1. Download a new copy of the Firefox installer from http://www.mozilla.com/
  2. Delete the Firefox installation directory, default location C:\Program Files\Mozilla Firefox\
  3. Re-install Firefox

User data is not stored in the installation directory and will still be available when you re-install Firefox.
