title: Replicating Google Chrome Browser Actions popup Effect in a Firefox Extension
body: <p>Chrome Browser Actions provide a really nice popup effect by default. </p>
  
  <p><em>dead ImageShack image link removed</em></p>
  
  <ul>
  <li><p>Hovering over the toolbar icon provides a neat hover effect. </p></li>
  <li><p>Clicking the toolbar icon shows a nice animation that opens the popup html file.</p></li>
  <li><p>The popup is aligned with the button that is pressed.</p></li>
  <li><p>Clicking the toolbar icon again fades out the popup.</p></li>
  </ul>
  
  <p>Any thoughts on how to approximate this effect with Firefox extensions? Has anybody successfully achieved something similar to this effect?</p>
  
  <p>Thanks.</p>
