Sorry to hear about your problems.

Go to Download Firefox v3.6.16 and download it to the desktop.

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.

After you complete the installation, go to the Plugins Check page and update those if necessary.
