Disable WebRTC
WebRTC exposes your internal network IP(s), without user interaction.

Disclaimer: Firefox Hello, and sites built on WebRTC including Airbnb, car2Go, and UberConference cannot be used with Disable WebRTC. If you are not benind a VPN you will benefint from only partial disable WebRTC with Fat-Free Fox: "WebRTC Private IP Address Leak: Note that enabling this option will only block private IP address leak due to WebRTC. It will not disable WebRTC completely. Firefox Hello would still be usable as before."

WebRTC is a communication protocol that relies on JavaScript that can leak your actual IP address from behind your VPN, by default. This addon fixes that, making VPNs more effective [1].


Source code is available here:

If there's an issue with the plugin, please let me know:

Note: For a span of time, this plugin switched to using the newer `` setting. This setting claimed to secure WebRTC, without needing to disable it entirely. Some users pointed out the new setting actually doesn't block private IP address leaks for certain VPN configurations. After that I switched it back, not wanting to endanger anyone.
