title: mediaelement.js: Getting videos to work in Firefox
body: <p>This seems like a common issue but I have not found any questions that have an answer marked so thought I would create one in hopes of finding a solution.</p>
  
  <p>My videos work fine in Chrome and Safari but when it comes to Firefox it doesnt display at all.. my CMS is ExpressionEngine if that helps any.  Does anyone have experience with this?</p>
  
  <p>The inserted code for the video on the page:</p>
  
  <pre><code>&lt;video width="640" height="360" preload="none" controls="controls" poster="http://site.com/img.jpeg" id="player1" type="video/mp4" src="http://site.com/content/videos/videotest(360p_H.264-AAC).mp4" tabindex="0"&gt;&lt;/video&gt;
  </code></pre>
