About WebRTC
WebRTC creates direct connections between devices. It can also reveal your real IP address even when you're using a VPN. This is called a WebRTC leak. A leak doesn't expose your activity or browsing history, but it can reveal your true IP address, which may show your approximate location.
How to Fix WebRTC leaks?
Chrome/Edge:
Unfortunately, there are no built-in toggles for WebRTC; thus, a third-party extension could potentially serve as a workaround.
Search for an extension like "WebRTC Control" or "WebRTC Leak Prevent"
Brave/Opera:
Menu > Settings > Search "WebRTC."
Set to "Disable non-proxied UDP."
Restart.
Firefox
Type about:config > Accept risk.
Search media.peerconnection.enabled > Set to false.
Restart.
Tor Browser
WebRTC disabled by default—no action needed.
Pair with a VPN that blocks WebRTC for full coverage.
