How to Fix WebRTC Leak in Chrome Edge and Brave Browser

Different Chromium browsers, different solutions

Chrome, Edge, and Brave are all built on the Chromium engine, so they all support WebRTC — and they all have the same fundamental WebRTC IP leak vulnerability. But each browser exposes slightly different controls, and the best fix varies.

Fixing WebRTC leaks in Chrome

Chrome removed the 'chrome://flags/#disable-webrtc' flag in recent versions. There are no built-in user-facing settings to control WebRTC IP handling in Chrome's main settings interface.

The practical solution for Chrome is a browser extension. WebRTC Privacy Shield is a Chrome extension that sets the 'WebRtcIPHandlingPolicy' via Chrome's extension API. Install it from the Chrome Web Store and it handles the configuration automatically.

• Default recommended settings for Chrome:
• Mode: "Default public interface only"
• This routes WebRTC through your default interface (your VPN, if you're connected) without disabling WebRTC entirely

Verify: visit browserleaks.com/webrtc and confirm your real IP doesn't appear.

Fixing WebRTC leaks in Microsoft Edge

Edge has a built-in WebRTC leak prevention setting. In Edge:

1. Go to Settings (three dots menu → Settings)
2. Click "Privacy, search, and services"
3. Under "Security," find "Prevent sites from detecting my network configuration using WebRTC"
4. Toggle it on

This built-in setting sets the equivalent of 'default_public_interface_only' mode. For most users, this is sufficient — run the leak test to confirm.

If you're still seeing a leak after enabling this setting, or if you want more granular control (per-site configuration, logging), installing WebRTC Privacy Shield in Edge (it's compatible since Edge supports Chrome extensions via the Microsoft Edge Addons store) adds that layer.

Fixing WebRTC leaks in Brave

Brave has the most complete native protection. In Brave:

1. Go to Settings → Privacy and Security → WebRTC IP Handling Policy
2. You'll see options: Default, Default Public And Private Interfaces, Default Public Interface Only, Disable Non-Proxied UDP

For VPN users, set it to "Default Public Interface Only." This routes WebRTC through your VPN interface without disabling WebRTC.

For maximum protection (breaks WebRTC functionality): "Disable Non-Proxied UDP" or install uBlock Origin with WebRTC disabled.

Brave's built-in setting is good enough for most users. The leak test should pass after configuration.

Testing all three

For any browser, the test is the same:

1. Connect your VPN
2. Visit browserleaks.com/webrtc or ipleak.net
3. Confirm only your VPN IP appears in public IP addresses
4. Local IPs (192.168.x.x) appearing is expected and fine

Re-test after every browser update. Chromium updates can sometimes reset or alter WebRTC IP handling behavior.

Using WebRTC Privacy Shield across browsers

WebRTC Privacy Shield is available as a Chrome extension and is compatible with Chrome, Edge, and Brave (all of which support Chrome extensions). If you use multiple Chromium browsers, installing it in each one is simpler than managing each browser's native settings separately.

The extension provides a consistent interface and the same protection across all three, plus a log of WebRTC access attempts that the native settings don't provide.

Conclusion

Brave has the best native WebRTC protection. Edge has a built-in setting that works. Chrome requires an extension. For all three, WebRTC Privacy Shield provides a consistent, testable solution. Run the leak test to confirm your configuration is actually working — don't assume it is.
