title: jQuery: event.preventdefault not working with Firefox (mac and PC)
body: <p>I have this bit of jQuery toggling a paragraph after an H3 link. It works in IE and Chrome on PC and Safari and Chrome on Mac. On Firefox on both platforms, clicking the link does nothing at all?</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
  $(document).ready(function(){
  $("#rightcolumn .article .collapse").hide();
  $("#rightcolumn h3 a").click(function(){
  if(event.preventDefault){
  event.preventDefault();
  }else{
  event.returnValue = false; 
  };
  $(this).parent().next().toggle(400);
  });
  });
  &lt;/script&gt; 
  </code></pre>
  
  <p>If I disable the event.preventDefault(); section it works in Firefox, but of course then I get the page jumping to the top which I don't want. What can I do to get it working in Firefox?</p>
