Disable WebRTC per Logan Marchione

WebExtension that disables WebRTC

To ensure your IP address does not leak while using a VPN (or another IP-masking technology), this extension disables WebRTC in Firefox 57+ by using the new API for browser.privacy.network.peerConnectionEnabled
https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/privacy/network

Confirm the setting with the URL below. It should be set to "false".
about:config?filter=media.peerconnection.enabled
