When you have disabled toolbar hiding in fullscreen mode, this specific Flash video doesn't get played in fullscreen. Instead the toolbars are still visible.

Steps:
1. Start with a fresh profile
2. Set 'browser.fullscreen.autohide' to false
3. Open http://www.youtube.com/watch?v=Zku6NfF5tQA
4. Click on the Flash movie fullscreen button

With step 4 I expect to see the video in Fullscreen. Instead the browsers toolbars are still visible. That seems to only happen on 10.7. I can't reproduce it on older versions of OS X.

Are you sure that this particular video is using Flash? I've run into a similar issue with full-screen HTML5 video (using the DOM full-screen API), but not with Flash.

You are right. This is the problem for this particular video. Thanks for mentioning that. Moving the the right component.

So, if the user disables toolbar hiding in fullscreen mode, you think toolbars should still hide when they enter fullscreen mode? INVALID?

The two use-cases are quite different. Ideally, a user shouldn't be forced to choose between usable full-screen browsing and usable full-screen video. As it stands, this situation is a "regression" from Flash video, where it is easily possible to have both.

Actually, I would be surprised if the present behaviour were deliberate. I had assumed that it was just a side-effect of re-using the regular full-screen code for the DOM full-screen API, without taking into account the effect of the 'browser.fullscreen.autohide' preference.

Our HTML5 fullscreen code is separate from the Fx UI fullscreen code now.
