body: <p>I'm using video.js, I've tried using ogv and now webm. Neither will play in Firefox 25. Site is <a href="http://www.hybi.info" rel="nofollow">http://www.hybi.info</a></p>
  
  <pre><code>&lt;video id="intro" class="video-js vjs-default-skin" width="498" height="365" 
  data-setup= '{"controls":true, "autoplay": true, "preload":"auto"}'&gt;
  &lt;source src="/images/intro.mp4" type="video/mp4"&gt;
  &lt;source src="/images/intro.webm" type="video/webm"&gt;
  &lt;source src="/images/intro.ogv" type="video/ogg"&gt;
  &lt;/video&gt;
  </code></pre>
  
  <p>Prior to using video.js I got</p>
  
  <pre><code>Video format or MIME type is not supported. 
  </code></pre>
  
  <p>Works fine in Chrome. What's the deal?</p>
