Is this behavior different from previous versions, say 3.6.8? Full screen browsing is supposed to display just the content. If you hover over the top of the screen, your controls should come back.

I am not able to launch my previous FF, so I can't tell.
The controls don't come back when I hover to the top of the screen.

You say, that when you move your mouse to the top border of you screen doesn't show the toolbars? Have you tried it already in Safe Mode or a fresh profile? Is that reproducible then? Would be great if you could create a screencast with Jing (http://jingproject.com/).

Otherwise it is expected behavior that the toolbars gets hidden by default. You will have to disable it via the context menu of the toolbars in fullscreen mode.

Can't see anything wrong on my XP box.

Update: I just noticed that this happens only when the menu bar is collapsed into the Firefox (or Minefield for nightly builds) button. When the full menu bar is visible, fullscreen works as it should.

As indicated by Dão Gottwald, this seems to be an issue from bug #575870 and how the titlebar and caption buttons are implemented and seems to be windows specific (though comments in #575870 indicate it is vista and win 7).

Could someone check if this bug appears on a non-microsoft OS?

I just checked the nightly builds and this bug was not present in the 4.0 branch until 2010-08-13.

Note to developers:
I went through bug #575870, and I think some code submitted on 2010-08-12 or 13 caused the 2010-08-13 nightly build to have this. 

Is there any way to track http://hg.mozilla.org/mozilla-central/ for changes made during this time? (I usu. use SVN and am not familiar with mercurials).

Is bug 582231 a dupe of this? (They have the same screen shot.) This might be related to tab candy.

Doh, I meant bug 587209, which is now fixed. This should be too. WFM beta5pre.
