How do I disable WebRTC in Firefox?

In Firefox, type about:config in the address bar, search for media.peerconnection.enabled, and set it to false. This completely disables WebRTC and prevents IP leaks.

How do I disable WebRTC in Safari?

Safari has WebRTC disabled by default for most users. If enabled, go to Safari > Preferences > Advanced > Show Develop menu, then Develop > Experimental Features > Remove Legacy WebRTC API.

How do I disable WebRTC in Brave?

In Brave, go to Settings > Privacy and security > WebRTC IP Handling Policy and select 'Disable non-proxied UDP'. This prevents WebRTC from revealing your real IP.

Can WebRTC leak my IP on mobile?

Yes, WebRTC can leak your IP on Android and iOS browsers. On Android, use Firefox with WebRTC disabled or Brave browser. On iOS, Safari has limited WebRTC exposure, but using a VPN with leak protection is recommended.

Detected IP Addresses

What This Means

WebRTC Leak: When your browser exposes your real IP address through WebRTC (Web Real-Time Communication), even when using a VPN. This can reveal your identity to websites.

Local/Private IPs: Addresses like 192.168.x.x or 10.x.x.x are internal network addresses. While less sensitive, they can still be used for fingerprinting.

Public IPs: Your real public IP address. If this appears while on a VPN, your VPN is leaking your identity.

Disclaimer: Modern browsers may mask local IPs using mDNS (.local addresses); results vary by browser, extensions, and VPN configuration.

How to Fix WebRTC Leaks

Firefox: Disable WebRTC by going to about:config and setting media.peerconnection.enabled to false

Chrome/Edge: Install a WebRTC blocking extension like "WebRTC Leak Prevent" or "uBlock Origin" (with WebRTC blocking enabled)

Use a VPN with WebRTC protection: Many premium VPNs include built-in WebRTC leak protection that blocks these requests

Use browser privacy mode: Some browsers block WebRTC in private/incognito mode or with enhanced tracking protection

Test again after changes: After applying fixes, run this test again to verify WebRTC is properly blocked

How This Test Works

We create a WebRTC peer connection in your browser
The browser gathers ICE (Interactive Connectivity Establishment) candidates
These candidates may contain your local, private, or public IP addresses
We analyze the candidates to detect any exposed IP addresses
If public IPs are found while using a VPN, this indicates a WebRTC leak

Privacy note: This test runs entirely in your browser. No IP addresses are sent to our servers.
