Hi, I am forced by my employer to use Firefox 3.6 to run a program which they wrote which they claim is not compatible with firefox 4 - which I have just installed on my Mac. Can you tell me how to re-install Firefox 3.6 please? Cheers Chris

Sure.

  • Then go to Add/Remove Programs, scroll down to Mozilla Firefox and remove it, choosing to keep your bookmarks, customizations etc., (don't checkmark the box).
  • Then reboot and delete the folder called Mozilla Firefox at this location: C:\Program Files\Mozilla Firefox
  • Finally run the installation file you downloaded to the desktop earlier.
