For some reason my Firefox Bookmark toolbar was blank, yet going to bookmarks, Bookmark toolbar folder showed all of the links there so the data wasn’t completely gone. Doug has a solution of restoring the default set which didn’t work for me until I disabled all extensions (using MrTech’s install extension), restarting firefox, right clicking the empty toolbar, selecting customize and then clicking Restore Default Set. That brought back all the links to the Bookmark toolbar. I then enabled all extensions, restarted firefox and everything is almost fixed. I still have an issue with Web Developers Toolbar being blank and if I click Restore Default Set I loose all the links again.
