WebRTC Control is an extension that brings you control over WebRTC API in your browser. 

The toolbar icon serves as a toggle button that enables you to quickly disable or enable the add-on (note: the icon will change color once you click on it). This addon does not a have toolbar popup UI. When WebRTC is enabled in your browser, your real IP address will be exposed to the public (even if you're using a masking service such as VPN). But preventing WebRTC leaks helps you protect your IP address. WebRTC Control add-on will also disable the following WebRTC components (see add-on options page):

  a. navigator.getUserMedia 
  b. window.MediaStreamTrack
  c. window.RTCPeerConnection
  d. window.RTCSessionDescription
