After my recent update on my Mac, Firefox doesn't work with fullscreen video.* This applies to websites like YouTube, Netflix, or other video based websites. I can enter fullscreen video, but on my Mac it doesn't fill the entire screen.

  • I am not talking about fullscreen for the Firefox window (that works fine), I am talking about specifically fullscreen video watching.

That is an issue on Mac where Full Screen mode is behaving differently.

In Firefox 56 you can still use this Legacy extension, but Firefox 57+ only suports WebExtension and no longer legacy extensions.

That Old Lion add on still doesn't really fix the problem, is there another solution?
