Support means that Apple has APIs for it. https://developer.apple.com/documentation/appkit/nswindowdelegate/1419563-windowwillenterfullscreen?language=objc htt

  It seems that in some cases, the way Firefox is calling those APIs is incorrect, or causes undesirable behavior.

    Who the fuck knows what's happening in Wowfunhappy's screenshot. I doubt it's because of the native fullscreen because it's something that's been a part of macOS for the past 8 years. And again, Firefox is already using the native fullscreen functionality in some cases. The issue is that some of the time it's not actually a fullscreen application and is merely just pretending to be one.
