  <p>I have a small script that animates background positions, sadly it doesn't work in FireFox.<br>
  It works in IE and Chrome.  </p>
  
  <pre><code>$('#background').animate({
       'background-position-x': -1020
  });
  </code></pre>
  
  <p>How come it doesn't work in FireFox?<br>
  Thanks in advance!</p>
