If there's a little double arrow pointing upwards in the lower right corner of your screen, clicking it will bring up the toolbar. If nothing is there, make sure you have scripts enabled. Otherwise, if you added any custom CSS or JS there could be an error breaking things. That's about all I can think of that could cause that.
