Example: I'm on YouTube. I play a video. I click to expand to full screen. It SLOWLY slides stuff over. It SLOWLY expands to fill the screen. Was this someone's seriously lame attempt at trying to be cool? This wasn't always like this. And Safari is still: click the full screen icon and it's full screen INSTANTLY.

It is possible that they both have the same effect. I don't know about that, so you would have to check that with the extension disabled. I also do not know if that setting is saved and persists after you close and restart Firefox.

I think that that is how switching to full screen works on Mac.

You can try to run this command in the Browser console:

FullScreen.useLionFullScreen = false

Does this extension helps?

Thank you! I installed the Lion add on and it helps a lot. There's a slight pause before instant full screen. I can live with that, thank you. Should I also type the command line in the browser console?
