When I open in Google Chrome some web-page with HTML5 VideoPlayer embedded and go fullscreen the player becomes "attached" to the separate desktop, so I can switch back to the original desktop with three-finger Touchpad-swipe. Fullscreened player remains fullscreened in "background" (more correct to say "at secondary desktop") In Firefox fullscreened player stays at original desktop. I'm migrating to FireFox and I'm just wondering if I could achieve the same behaviour here like in Google Chrome?
