My toolbar has completely disappeared. I still have the back arrows on the far left, but everything else is just ... gone. I've tried stopping Firefox and restarting several times, but nothing is changing. All the toolbars are checked in the view menu.

July 13th, 2010: My Firefox tool bar has suddenly completely disappeared, except for the back arrows on the left hand side. I've tried stopping and starting Firefox several times, but nothing's changed. All the toolbars are selected in the View menu ... but nothing's visible!
