How to disable WebRTC in Chrome on desktop

There are two Chrome extensions known to successfully block WebRTC leaks:

1. uBlock Origin
2. WebRTC Network Limiter

uBlock Origin is a general all-purpose blocker that blocks ads, trackers, malware, and has an option to block WebRTC. WebRTC Network Limiter is an official Google add-on that specifically stops IP leaks without totally blocking WebRTC.

How to disable WebRTC in Safari on desktop

There’s no need to disable WebRTC in Safari. Safari’s permissions model is stricter than those of most browsers. By default, no IP addresses are made available to websites except the one you use to access the site. Therefore you shouldn’t need to take any additional action to prevent WebRTC leaks in Safari. Note, however, that if you grant any particular site permission to use audio or video capture, you might expose your IPs.

How to disable WebRTC in Microsoft Edge

Unfortunately, there’s currently no way to completely disable WebRTC in Microsoft Edge. However, you can set your browser to hide your local IP address if you:

1. Type about:flags into the address bar
2. Check the option marked Hide my local IP address over WebRTC connections

As mentioned above, revealing your local IP address is not a threat to your privacy, so the steps above offer little benefit. Therefore the best way to stop WebRTC leaks while using Microsoft Edge is by using the IPBurger VPN app for Windows.

*Disabling WebRTC probably won’t affect normal web browsing. Most websites don’t depend on it… yet. But as WebRTC becomes more popular, the functionality of certain sites may decline if you disable it completely.
