Fullscreen youtube on it's own desktop on mac

[sabai-battai]

If I fullscreen a youtube page, please update it on a new dessktop, instead of fullscreen on same desktop, so that I can switch between screen with trackpad

For me full-screen-api.macos-native-full-screen set to true helped (write in the address bar about:config). I hope I understand what you mean.
