Normally, the Bookmarks Toolbar is below the address bar. However, it is possible to move the bookmarks to another bar by going into Customize and dragging the "Bookmarks Toolbar Items" there. Knowing that, you could try using Customize to move the "Bookmarks Toolbar Items" back where they belong. Make sure the (blank?) Bookmarks Toolbar is showing. More info on Customize: [[Customize Firefox controls, buttons and toolbars]] If drag and drop doesn't work, try the "Restore Defaults" button near the lower right of the panel. Can you get your bars straightened out?
