In addition to UI spoofing there is also the "annoying websites" factor. There is today API for pages to resize the browser window, which I know that some pages abuse to resize the browser window to be as big as possible. This API is one of very few that Firefox has specific API to turn off, because its one of the APIs that annoy users the most. As for flash going full screen. I heard something regarding that while in full screen mode flash disables certain capabilities, in order to reduce the risk of spoofing. Such as the ability to receive keyboard events. Haven't investigated this at all though. I'm also not sure what you mean by "can probably figure out if they are in full-screen mode or not". How would you figure this out? Other than by installing a non-standard skin for your desktop or browser? / Jonas
