Hello. I am currently trying to play a web game, but something is very annoying. The game doesn't implement pointer lock, so I have to play fullscreen for the movement to be continuous. Unfortunately, every time my mouse passes past the top of the screen, Firefox automatically unhides the titlebar and controls, and over all tries to escape fullscreen mode. This is very bad for the game, as the mouse movements are frantic and need a continuous mouse. How can I disable this behavior, so that Firefox keeps everything hidden in fullscreen until F11 is pressed?

You can use CSS code in userChrome.css to hide the #fullscr-toggler element.
