title: Kaltura embedded iframe player error on Firefox
body: <p>I'm trying to embed a video from Kaltura Video Platform in a HTML5 page. </p>
  
  <p>I followed <a href="http://knowledge.kaltura.com/embedding-kaltura-media-players-your-site" rel="nofollow">the docs</a> at Kaltura. So far I'm able to play the video in Safari, Chrome and Internet Explorer but it fails to load in Firefox. The firebug console shows this javascript error:</p>
  
  <blockquote>
    <p>ReferenceError: kWidget is not defined</p>
  </blockquote>
  
  <p>The HTML5 code demostrating the issue follows (see <a href="http://jsfiddle.net/ELjbw/1" rel="nofollow">fiddle</a> for a live demo):</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
  &lt;title&gt;test&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
      &lt;iframe id="iframe_-1" src="http://www.kaltura.com/p/403921/sp/40392100/embedIframeJs/uiconf_id/4438451/partner_id/403921?iframeembed=true&amp;amp;playerId=iframe_-1&amp;entry_id=1_40ttmxyq" width="400" height="330" allowfullscreen webkitallowfullscreen mozAllowFullScreen frameborder="0"&gt;
          &lt;a href="http://corp.kaltura.com/products/video-platform-features"&gt;Video Platform&lt;/a&gt;
          &lt;a href="http://corp.kaltura.com/Products/Features/Video-Management"&gt;Video Management&lt;/a&gt; 
          &lt;a href="http://corp.kaltura.com/Video-Solutions"&gt;Video Solutions&lt;/a&gt;
          &lt;a href="http://corp.kaltura.com/Products/Features/Video-Player"&gt;Video Player&lt;/a&gt;
      &lt;/iframe&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>What puzzles me is that only Firefox is complaining. Has anybody experienced the same issue? Is some sort of cross-domain issue?</p>
