If I enter a fullscreen on a website(and firefox is in fullscreen mode), youtube for example, it goes in another Mac window, which is really weird for me. Because I want it to just stay on this window and be fullscreen also. How can I do it? But that's the only one part of a question, then if I exit a fullcreen youtube video, the window slides back to firefox with unwanted animation and gets unfullscreened, but then firefox also go to not fullscreen. Expected: 1) When I open video or something in a fullscreen, it should stay on firefox window, not create another one and slide in it. 2) When I switch back to normal mode on video, and not fullscreen and when it slides back to firefox window firefox should stay fullscreen.

PS: I figured that it is only occurs with flash, when I use HTML5 features it is all cool. Still need to fix this coz there're only small part of sites use HTML5

System: Mac OS X 10.10/ firefox 38.0/Shockwave Flash 18.0 r0

Since you are already in full screen, exiting out of fullscreen on youtube then the whole Firefox window will go out of full screen. It is possible to accomplish this with Mac's many desktops. Open youtube in a new window full screen and you can swipe between them when the video closes.

It is also possible to customize this with:
