title: Firefox: navigator.getUserMedia is not a function
body: <p>I'm playing with browser and audio.</p>
  
  <p>I'm doing this</p>
  
  <pre><code>        var session = {
            audio: true,
            video: false
          };
          var recordRTC = null;
          navigator.getUserMedia(session, initializeRecorder, onError);
  </code></pre>
  
  <p>But, using latest FF available I got a javascript error, saying that</p>
  
  <blockquote>
    <p>navigator.getUserMedia is not a function</p>
  </blockquote>
  
  <p>I copied this code from this blog post: <a href="https://blog.groupbuddies.com/posts/39-tutorial-html-audio-capture-streaming-to-nodejs-no-browser-extensions" rel="noreferrer">https://blog.groupbuddies.com/posts/39-tutorial-html-audio-capture-streaming-to-nodejs-no-browser-extensions</a></p>
  
  <p>And similar on latest Chrome:</p>
  
  <blockquote>
    <p>Uncaught TypeError: undefined is not a function</p>
  </blockquote>
  
  <p>But I know that this api is supported from both browser</p>
  
  <p>What am I doing wrong?</p>
