title: How to access Web camera from Geckofx?
body: <p>I'm making an original web browser based on GeckoFX-29-Windows.</p>
  
  <p>How to allow access web camera from original Web browser?</p>
  
  <p>For example, access to <a href="https://appear.in" rel="nofollow">https://appear.in</a> by Firefox, it appears a dialog to use Web camera.
  But I can not figure out a web camera access method.</p>
  
  <p>Would you please let me know how to use web camera from GeckoFX?</p>
