title: Recording in HTML5 does not work in Firefox
body: <p>I am using recorder.js and Recordmp3.js for recording audio through microphone.</p>
  
  <p>It's working fine in chrome browser but not in Firefox(Latest version as well).</p>
  
  <p>When I hit my web app on the Firefox browser, It asks me to share microphone but after few seconds It gets disappeared. So because of that recording feature not be able to record anything on Firefox.</p>
  
  <p>I am sharing on working example developed using Recordmp3.js and It's not working in Firefox.</p>
