timer not working in FF

This is only showing maybe one div row in FF not sure why. But works ok in IE.

<!-- body tag -->

  <div id='Timer0' 
                            style="display:none;">
                            12/27/2011 12:00:00 AM</div>
                        <div id='Timer0d'></div>
                        
                         <div id='Timer1' 
                            style="display:none;">
                           12/22/2011 12:00:00 AM</div>
                        <div id='Timer1d'></div>

     <div id='Timer2' 
                            style="display:none;">
                           12/29/2011 12:00:00 AM</div>
                        <div id='Timer2d'></div>
