Firefox3 has a brand new way to create bookmarks, and the old way gone for good. While it is a bit better, I've heard complains from testers about the lack of a button to create new bookmark folders. It is possible to associate the bookmark to already-created folder, but I can't see any easy way to create there new folders. Maybe we would prefer the users to use tags instead, but we need to allow them to organize in folders too. Maybe even to require them to go though the preferences to add that missing button.
