How to disable WebRTC in Google Chrome for Desktops:

Simple Explanation: You can’t. Use a Chrome Extension or switch Web-Browsers.

Detailed Explanation: For some crazy reason Google never added an option in settings to disable WebRTC, even with all the complaining online through social media and forums, even their own forums. Here are the three most popular WebRTC blocking extensions for Chrome.

• WebRTC Leak Prevent – Has three modes of operations and an on/off toggle button.. 91,986 Users, 225 Ratings, 3.89 Stars.
• WebRTC Control – Has an on/off toggle button, no options. 26,954 Users, 42 Ratings, 4.64 Stars
• Easy WebRTC Block – No options, no on/off toggle button. 10,435 Users, 19 Ratings, 4.37 Stars

Another option would be uBlock Origin if you want to block advertisements and pop-ups along with WebRTC Leak Scripts. However, a major concern with using any of the “WebRTC Leak” blocking extensions for Chrome is that they only block scripts that get your IP from the leak from running on websites, but the leak is still actually there and not fixed at all.

No matter which method used, Test for IP Leaks when done using this WebRTC Leak Checker.

How to disable WebRTC in Microsoft Edge for Desktops:

Simple Explanation: You can’t. There is a way to at least stop WebRTC from leaking your Local IP address – In “about:flags” tick the box next to “Hide my local IP address over WebRTC connections”.

Detailed Explanation: Microsoft screwed around for a while developing their own WebRTC alternative, ORTC, in true Microsoft form, and support for WEbRTC was delayed. Microsoft did eventually add WebRTC capabilities to Edge browser on Windows 10 build 15019 and later, but not Internet Explorer. Sadly, there is no way to disable WebRTC in Edge, it can only be adjusted to not reveal Local IP addresses.

1. Navigate to “about:flags” using the address bar.
2. Check the box next to the “Hide my local IP address over WebRTC connections” option.
3. Test for IP Leaks using this WebRTC Leak Checker.

Simple Explanation: You can’t. Use a Opera Extension or switch Web-Browsers.

2. Go to WebRTC Leak Prevent’s preferences, and set the top setting’s drop-down to be “Disable non-proxied UDP (force proxy)”.
3. Check the “Prevent WebRTC from using non-proxied UDP” box.
4. Test for IP Leaks using this WebRTC Leak Checker.

Another thing to consider would be the uBlock Origin extension for Opera if you’d like to block WebRTC Leak Scripts as well as pop-ups and adverts.
