I lost the the Yahoo! Toolbar from the FF browser, spent hours on the phone w/ ATT/Yahoo to no avail, however the next AM the toolbar reappeared. I just upgraded to FF4 and again lost the Yahoo! Toolbar. I have downloaded the Toolbar supposedly optimized for FF4 several times, rebooted my computer but no luck. Yahoo! has a large list of my bookmarks, I really need to be able to access it.
