Title pretty much says it all. I cannot drag tabs to bookmark menu without closing and then reopening bm menu. Then it will last for a while that I can drag tabs to menu but at some point I can no longer drag tabs. When I drag a tab I get a little picture of the tab url page but no line showing where the tab can be dropped. A corollary to this problem, I think, is that Bookmark Toolbar will not remember overnight the changes I have made. It will remember the changes through a restart and so far, for the rest of the day. But the next morning, the bookmarks are back to what they were, all jumbled up. I have removed and reinstalled FF, I have refreshed it, I have taken ALL the add-ons off (including the one I use all the time, roboform) and the problem has persisted over several days. I can't remember when exactly it started but a week ago everything was fine, I was using xmarks and roboform with not problem and one day I could no longer sync with xmarks and my bookmarks were all messed up.
