What is WebRTC?
It is an extension built into modern browsers (Chrome, Firefox, Opera...), which allows you to establish audio and video conferencing without the use of third-party programs.
What is WebRTC Leak?
It is a leakage of the real IP address when the WebRTC is enabled. Through this plugin sites can get your real IP address and a list of all IP addresses of the active network interfaces. That means that even when connected via Proxy/VPN, your real IP address and location can be identified.
How to prevent WebRTC Leak?
If you use Firefox, you can disable WebRTC through browser settings. In other cases, you should use an extension (e.g., WebRTC Network Limiter for Google Chrome).
The best choice is to use utilities to hide IP address and to encrypt traffic with built-in protection against WebRTC Leak (e.g., Privatix).
How to disable WebRTC in Firefox:
Type in the address bar: about:config and press the “I’ll be careful, I promise!".
Find in the new window using a search tool: media.peerconnection.enabled
Right-click the line and click “Toggle” in the menu that appears.
In the “Value” column value changes from “true” to “false”.
- Restart your browser.
