I used the pull down menu on the firefox icon on the left hand upper corner to create a full a screen. Once the full screen was created the icon disappeared and I cannot go back to regular screen. HELP.

If you run Firefox in full screen mode then press F11 or Fn + F11 to toggle (Mac: command+Shift+F).

If you are in full screen mode then hover the mouse to the top to make the Navigation Toolbar and Tab bar appear.

You can click the Maximize button at the top right to leave full screen mode or right click empty space on a toolbar and use "Exit Full Screen Mode" or press F11.


  • Press F10 or tap the Alt key to bring up the "Menu Bar" temporarily if the Menu Bar is hidden.
  • Use "Firefox > Options" instead of "Tools > Options" if the menu bar is hidden.
