title: Firefox WebSockets
body: <p>I've read somewhere that the trunk version of Firefox already had a WebSocket implementation. Nevertheless, I've just tried the 3.7a4pre without success. It still 
  gives me the old "WebSocket is not defined" error message. Am I confused with WebWorkers?</p>
  
  <p>Using a flash-based WebSocket implementation is not an option.
  Please advice.</p>
