If you toggle Firefox in full screen mode there remains in the top the address and navigation bar with OS buttons on right side (minimize/window size/exit).
Is there any idea how to hide the OS buttons, at least the exit button? I couldn't find a command or style for it.
This style would be useful for a public computer, where everyone may use Firefox. But some of the users use to shut down Firefox when they leave.
Hoping for a suggestion!
