I have upgraded to 4 but it just shows tool bar and blank page and will not open any bookmarks. I had no problem with 3.6 and want that version back.

Sorry to hear about your problem.

  • 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.
