Fuller Screen - using entire screen for browsing

Fuller Screen is a extension that enhances the existing Firefox Full Screen mode into a really full screen mode, hiding the remaining toolbars and statusbar and making them visible again when the mouse pointer hits an edge of the screen - more like a autohide mode

The autohide seems to be a little flaky though - and I am not sure if too many people use Fullscreen anyway - I am trying it out and finding a little hard to get adjusted - thats primarily because I use Live BookMarks, a lot of extensions like Firebug, del.icio.us, Foxclocks which reside on the toolbars.

Give it a try
