Full flash page problem with FireFox

I’ve been working to through the Full Screen Flash Page tutorial, but my efforts can not make the page full screen in the Firefox broswer. Even the example swf that the author of the tutorial has for us to view does not render full screen in Firefox. It does however work in IE. Does anyone else have this problem? Is there a way to fix it? Perhaps this has been addressed elsewhere in which case if someone could point me with a link I would appreciate it.
