Is WebRTC Protect - Protect IP Leak safe?

Controls WebRTC network routing to limit exposure of public and private IP addresses.

This extension changes browser privacy settings for WebRTC, blocking WebRTC by default and requiring WebRTC traffic to use proxy servers when configured. A toolbar button can temporarily enable WebRTC, while private IP address protection remains enabled by default. It can also make the WebRTC Media Device Enumeration API return an empty array unless disabled from the toolbar button or options page.
