Is there a way to make Firefox use Mac's native fullscreen when watching a video (e.g. on Netflix)? The browser does go fullscreen, but it's not on it's own space on macOS.
I'm currently using Firefox 57 and macOS 10.13.1.

Unfortunately, that's not currently implemented in Firefox (see Bug 1403085).
As a workaround, consider putting Firefox itself into fullscreen mode by clicking the green button in the title bar before making a video fullscreen.
