How to Fix WebRTC Leaks in Firefox

Step 1: Disable WebRTC in about:config

Type about:config in the address bar and accept the warning. Search for:

media.peerconnection.enabled

Double-click to set it to false. This completely disables WebRTC in Firefox.

Step 2: Disable ICE Candidate Generation

For extra protection, also set these in about:config:

• media.peerconnection.turn.disable → true
• media.peerconnection.use_document_iceservers → false
• media.peerconnection.identity.timeout → 1

Step 3: Use NordVPN for Complete Protection

Pair Firefox's settings with NordVPN for the most thorough protection. NordVPN blocks WebRTC leaks at the network level, so even if a setting is reset, your IP stays hidden.

Step 4: Verify

Run our WebRTC Leak Test again. You should see "You're protected" with no leaked IPs.
