The folders in my bookmarks toolbar only display as a small white square when I click on them. Even when I try to display them from the Bookmarks menu. They are present because I can right click and choose "open all in tabs" and they will all open but I can't select individually or open a folder to see sub folders. I have tried deleting places.sqllite and localstore.rdf but that doesn't help. Deleting Places.sqllite allowed me to see one folder's contents but no sub folders. Then when I closed and reopened FF even that folder view was corrupt. I'm using FF4.01 on a windows 7 x64 home premium desktop.
