The Bookmarks Favicon Changer add-on gave me the capability that I had before to change the bookmark toolbar icons. Thanks! I did not use this add-on for FF3, before, but it gets the job done.

'''dave-o''': You are welcome. Bookmark Favicon Changer is a new add-on; it was developed to be compatible with Firefox versions 3.5, 3.6 and 4.0.
