Surprised that escape doesn't work to exit fullscreen.

I meant to mention that -- Firefox uses ESC to exit fullscreen but Chrome uses Cmd+Shift+F. They need to standardize that.

esc works for me on 17.0.942.0 dev on OS X

Ah yes, I'm on Chrome, and I figured that would be a pretty good way to get someone trapped in full screen.

Outside the mac world, "F11" is a pretty much universal "toggle full screen" binding. Chrome at least supports with on-screen help when you enter full screen mode.

It also works in Safari 5, surprisingly enough, with ESC to exit fullscreen mode.

Don't work on my Kubuntu (Chromium 13.0.782.215 (Build 97094 Linux) Ubuntu 11.04 ).

Nothing happens when I click the button.

EDIT: on Firefox too.

Hey that Gamepad API reads promising.

When is there ever going to be a download API?

This is great news for HTML5 game developers!

if you're on Chrome 15+, you can use fullscreen in my HTML5 game. http://chrome.private-joe.com

fullscreen button is bottom right, when the level loads.

I wonder how difficult it'd be to build a fullscreen browser replacement and have it load automatically. The fake browser could mimic real browser actions and easily mask the url (and all of the browser chrome, for that matter) and inject their own content when a user navigates to an interesting site. All the normal "safe" markers (e.g. green URL bar, security lock on the bottom right, the correct URL) could be shown to the user.

Hmm....

The only way that would be feasible is to use iframes, and you can't inject anything into an iframe.

It would be a technical challenge, but they could MITM your entire browsing experience. Fullscreen to canvas, then show what looks like a browser. When someone types something in the URL bar the attacker's backend proxies a request to the real site, loads the content, then renders a canvas page of it.

It would probably be too much work for too little payoff to actually make a browser that rendered to canvas, but they could do it for a couple of major target sites like gmail and banks.

To undo fullscreen in Chrome:

* Command/Shift/F

* Command/, (going into Preferences disables it)
