Whitelist for domains? I need it on for Threema Web messenger!

It's broke by the way.. But my question is - we use it for privacy but under permissions it states
Access your data for all websites
Read and modify privacy settings
What the heck.

WebRTC Control fails to prevent the private IP leak, and RTCPeer connection. You can test this by browsing to https://ipleak.net

You are better off manually changing the media.peerconnection.enabled from true to false by opening about:config

This extension does not work in firefox. It does not pass the test at https://browserleaks.com/webts and https://ipper.ru
But it works well in chrome, opera and yandex.browser.
