title: Firefox picture tag support?
body: <p>I'm trying to use <code>picture</code> tag in Firefox. <a href="http://caniuse.com/#search=picture" rel="nofollow">caniuse.com says that <code>picture</code></a> supported in Firefox 33 (beta) and I can enable support in Firefox 32 (current) manually. </p>
  
  <p>I opened an <a href="http://www.html5rocks.com/en/tutorials/responsive/picture-element/" rel="nofollow">example from html5rocks</a> and I can see that it doesn't work. Also I tried on my own <a href="http://vm-0.krasulya.kd.io/" rel="nofollow">http://vm-0.krasulya.kd.io/</a>. There are requests only to basic image (<code>src</code> attribute) in webinspector network panel.</p>
  
  <p>Both examples work in Chrome Canary.</p>
  
  <p>According to <a href="http://www.whatwg.org/specs/web-apps/current-work/multipage/edits.html#the-picture-element" rel="nofollow">http://www.whatwg.org/specs/web-apps/current-work/multipage/edits.html#the-picture-element</a> HTML is correct.</p>
  
  <p>Does FF support <code>picture</code> at all?</p>
  
  <p><strong>UPD</strong></p>
  
  <p>Here is my markup:</p>
  
  <pre><code>&lt;picture&gt;
      &lt;source
          src="1.jpg"
          type="image/jpeg"
          media="(min-width: 300px)"
          srcset="1.jpg, 2.jpg 2x"/&gt;
    &lt;img 
      src="1.jpg" 
      srcset="1.jpg, 2.jpg 2x"&gt;
  &lt;/picture&gt;
  </code></pre>
