Accordion Pane Stopped Working in FireFox Created Jul 2, 2010

Has something changed in the last few days with the accordion tab interface and FireFox. I have an accordion interface that was working just fine a couple of days ago. As of this morning, it still works in IE, but not in FF. The code I used duplicates the demo. Here is the snippet of my code...

<!-- include the Tools -->
<script src="http://flowplayer.org/tools/download/combine/1.2.3/jquery.tools.min.js?select=full&debug=true"></script>

<div id="accordion">
	 
                    <h2><a href="javascript:void;" class="headerlink">headline</h2>

<div class="pane">

yada...yada...yada...

</div>	
                </div>
                 
                <!-- activate tabs with JavaScript -->
                <script> 
//Switch the "Open" and "Close" state per click
$("h2").toggle(function(){
$(this).addClass("current");
}, function () {
$(this).removeClass("current");
});

//Slide up and down on click
$("h2").click(function(){
$(this).next("#accordion div.pane").slideToggle("slow");
});

                </script>

Thoughts?
