In some cases, different browsers experience WebRTC leaks that can cause real IP address leakage, even when using a VPN.
However, you can quickly disable WebRTC leaks.
Mozilla Firefox: Type about:config in the address bar. Scroll down to media.peerconnection.enabled, double click to set it to false.
Google Chrome: Just install this plug-in and it will prevent WebRTC leakage.
Opera: Type "about:config" in the address bar or go to "Settings". Select "Show advanced settings" and click on "Privacy & security". At "WebRTC" mark select "Disable non-proxied UDP".
