I have been troubleshooting for about an hour and nothing has worked yet. So I have about 20 bookmarks in the "Bookmarks Toolbar" library thing. When customizing, I drag the bookmarks toolbar tab to its usual area, and the words "Bookmarks Toolbar Items" appears, but once I exit customization, its empty. Nothing to click. Bookmarks Toolbar is checked during customization. I have dragged it around, re-installed Firefox and nothing. It seems like Firefox is not recognizing I actually have any bookmarks to display, regardless of how many I have just now made.
