linux Rated 3 out of 5 stars

In firefox 3.0.5 (original download from mozilla) for linux, after entering in full screen, one second later the window scrolls down a few pixels and show a few pixels of the upper menu. This can avoided by deselecting the "Hide toolbars" firefox option (unfortunately, enabled by default, I think). This is a bit annoying in order to create a web site easily usable in true full screen mode by novice users.
