Komunitné fórum Firefox

Hello,

I’m the developer of SnakeGame.Live , a browser-based multiplayer snake game with mouse steering on desktop.

I would like to understand the difference between Firefox’s F11 fullscreen mode and fullscreen activated through a website’s Fullscreen API.

For a mouse-controlled game, do these modes behave differently when the pointer reaches the top edge of the screen? Is there a recommended way to let players use fullscreen while keeping Firefox’s normal exit controls available?

I’m using Windows 10. I would appreciate guidance on the expected Firefox behavior and any relevant support documentation.

Thank you.
