Comment 22 for bug 225257

Don't have to delete ".mozilla"... I was wondering that Yoono's (an extension similar to del.ici.ous and GMarks) was involved in this problem since it was disabled in Firefox 3b. So, reading the fix from Lars and Russell, I just deleted this folders/files relative to this extension (and preserved after upgrade) in my .mozilla folder: bookmarkbakups (folder), yoono (folder), bookmarks.bak (file)... I added a new bookmark, closed firefox, open firefox and, now, my new bookmark was there!

Perhaps, the other bookmarks extensions has similar files in .mozilla dir and people involved just have to delete them to fix the problem, without lost their personal firefox configurations.
