 How to turn off WebRTC

WebRTC makes it easier for people to communicate between browsers without installing additional software. WebRTC allows you to chat, meet online or share files with others.

However, WebRTC can also expose a device’s local and public Internet address, even if you choose to hide the device’s location by using a virtual private network (VPN). This phenomenon is collectively known as a WebRTC leak, as it exposes the user’s personal information. Once an advertiser or web host knows a device’s public Internet address, they can determine the region, city, and Internet service provider associated with that address.

If you don’t need WebRTC, you may want to disable or restrict it in your browser. You can prevent a WebRTC leak in many modern browsers.

How to disable WebRTC in Firefox

Of all modern browsers, Firefox is the only one that allows you to completely disable WebRTC.

1. Open Firefox, then type about: config where you normally enter a web address and press Enter (or, on some other system it is Return).

2. Click the button I accept the risk! This gives you access to many Firefox configuration settings.

3. In the search box at the top, type peer and press Enter.

4. Double-click the row media.peerconnection.enabled. The row will display in bold, and the value will change to false, this indicates that peer-to-peer connections are now disabled.

2. Select the icon for Chrome, even if you are using the new version of Microsoft Edge.

3. Reminder “You can now add extensions from the Chrome Web Store to Microsoft Edge” will be displayed. Press Allow extensions from other stores.
