title: Flexslider fade issue
body: <p>I have seen lots of similar issued but none that resolve my problem. I am using flexslider 2.2.0 and when I implement the fade animation the function is broken in Firefox version 30. In IE, Chrome etc there are no problems. I use the following code</p>
  
  <pre><code>&lt;script src="site/flexslider/jquery.flexslider.js"&gt;&lt;/script&gt;
  
  &lt;script&gt;
  jQuery(document).ready(function($) {
      // You can use the locally-scoped $ in here as an alias to jQuery.
     $('.flexslider').flexslider({
          animation: "fade",
          slideshowSpeed: 10000, 
  
          });
  });
  &lt;/script&gt;
  </code></pre>
  
  <p>If I use the slide animation  then they are no issues on all browsers.</p>
  
  <p>I have tried </p>
  
  <p>Find &amp; Replace the code in flexslider.js:</p>
  
  <p>Find :
  eventType = (touch) ? "touchend" : "click",</p>
  
  <p>Replace:
  eventType = "click touchend MSPointerUp",</p>
  
  <p>and also removing:
  el.addEventListener('touchstart', onTouchStart, false);</p>
  
  <p>But still have the issue. </p>
  
  <p>Any ideas?</p>
