You can reinstall Firefox 3.6 from http://www.firefox.com/all-older.html

You might need to uninstall Firefox 4 before installing Firefox 3.6. When you uninstall Firefox 4, make sure you do not select the option to "Remove my Firefox data." (If you select that option, it will delete your bookmarks and settings.)
