Websocket HTML5 ReferenceError: WebSocket is not defined

Question

I have a very basic HTML5 page that connects to a websocket from javascript using :

var socket = new WebSocket("ws://localhost:5555");

I always get that error in FF10 : ReferenceError: WebSocket is not defined I've check the about:config and WebSockets are enabled.. What's going on??
