title: Misalignment of Facebook & Twitter buttons
body: <p>The page contains two buttons, from twitter and from facebook.</p>
  
  <p>What I'm observing in Firefox 3.5.15 is:</p>
  
  <ol>
  <li>While the page is loading, the buttons are more or less aligned (I mean their bottom sides)</li>
  <li>When the page is loaded, the facebook button moves a few pixels down, so that it's bottom side is lower than the bottom side of the twitter button.</li>
  <li>If I reload the page, the buttons are again aligned, and remain in this state even after the page is loaded.</li>
  </ol>
  
  <p>Can someone please explain what's going on and how to fix it?</p>
