How do you get back to no menu bar on the screen on Windows 7 and Firefox 20.0?
To get the menu bar there is the “Firefox” in a dark orange background at the left top of screen ( for Options—> Menu Bar) “Firefox” is no longer there, once menu bar is there. The back arrow is greyed out. So how do you undo it?
