title: Firefox 6 javascript in addressbar
body: <p>Whatever I type after "javascript:" in the address in firefox 6, firebug says "uncaught exception: ReferenceError: document is not defined". If I try window, it says "uncaught exception: ReferenceError: window is not defined." </p>
  
  <p>If I type the same code in the firebug command line, it works. What gives?</p>
