title: How can I communicate with serial port in Firefox?
body: <p>I have already developed a Chrome App and Extension to communicate with serial ports of a client using API from <a href="https://developer.chrome.com/apps/serial" rel="nofollow">https://developer.chrome.com/apps/serial</a>. 
  Currently I do the same operation in Firefox through a Java applet.
  Since support for Java applet will be deprecated soon, I would like to develop an addon for Firefox for this.</p>
  
  <p>The real problem is that I can't find any documentations in <a href="https://developer.mozilla.org/en-US/docs/Web/API" rel="nofollow">https://developer.mozilla.org/en-US/docs/Web/API</a> for an API able to work like the Chrome serial.</p>
