For example, the following snippet would fire a question dialog asking the user whether he wants this site to be able to set fullscreen mode: fullScreen = true; or setFullscreen(true); If the user wanted to, he would enable the site to be able to set fullscreen on / off. Just like with Flash, this would make better RIA's. Reproducible: Always Actual Results: Fullscreen only via F11.
