title: css3 transitions not firing first time in Firefox 4
body: <p>I am experimenting with some css3 transitions. I put together a quick slider test and it works well in the webkit family. In Firefox 4, the first time you click on the left link the slider is suppose to slide to the left, however, there is no css transition until the second time you click the link. I put the demo up on jsfiddle - <a href="http://jsfiddle.net/mrleroylee/ctY68/" rel="nofollow">http://jsfiddle.net/mrleroylee/ctY68/</a></p>
  
  <p>Is this a result of something in my code or is this a bug?</p>
