# How to Fix WebRTC IP Leaks in Chrome and Firefox

Practical settings and extensions to stop WebRTC from advertising your real IP while VPN is on.

Practical settings and extensions to stop WebRTC from advertising your real IP while VPN is on. Chrome / Chromium Chrome does not expose a simple “disable WebRTC” toggle. Use privacy-focused Chromium builds, enterprise policies, or reputable extensions that force relay-only mode. After changes, restart the browser and retest candidates. Firefox In about:config , set media.peerconnection.ice.default_address_only and related ICE prefs carefully, or disable peerconnection if you never need browser calls. Document what you change so you can reverse it for Meet/Zoom-in-browser. Trade-offs Hard-disabling WebRTC breaks some video calls. Prefer VPN + relay-only modes when you still need conferencing. Verification workflow Connect VPN Close all tabs that might hold old peer connections Run WebRTC + DNS + IP tests Join a test call only after privacy checks pass Related reading Pair with WebRTC leak basics and DNS leak prevention .
