Sounds pretty stupid, but it sounds like you should be able to get round it by sticking everything in a scrollable wrapper div (height:100%; overflow:scroll) when fullscreen mode gets activated. Or just do things the old fashioned way and tell the user to hit F11 (or apple-shift-F on mac) to put their browser into manual full-screen mode, which supports scrolling.

I did try this. I don't remember this exactly, but what was happening then is that only the visible part of the page came in to the F11 wrapper div. There no-scroll in the full-screen browser window.

In effect you're left with an option to introduce scrolls within content divs, and that looked worse. Chrome on the other hand manages this quite nicely.
