I clicked Firefox button and then clicked the full screen mode. I know wish to exit this mode but can not find the way to undo it
F11 toggles fullcreen mode.
You can also hover the mouse to the top of the screen to make the Navigation Toolbar and Tab bar appear. If you right click in empty space on either toolbar then you get a context menu with an "Exit Full Screen Mode" entry.
I have firefox 4,and F11 does nothing.BTW,can I totally hide all the toolbars with ff4,like the add-on Full Fullscreen does (not yet compatible with ff4) ?
Does Firefox (View) > Full Screen switch Firefox to full screen mode?
You can hover the mouse to the top of the page to make the toolbars appear and right click empty space on a toolbar (tab bar) to exit full screen mode.
