Firefox – easy method

Desktop and Android users can use the [Disable WebRTC plugin](https://addons.mozilla.org/en-US/firefox/addon/happy-bonobo-disable-webrtc/) for Firefox. Click on the "Add to Firefox" button and follow the instructions to install the plugin.

Once installed, it will disable WebRTC by default. You can check by looking for the plugin's 'W' icon in the Firefox toolbar. The plugin is working if the icon is green. Click it and it will turn red, meaning that WebRTC is enabled again.

Firefox – advanced method

Use these instructions if you wish to manually disable WebRTC:

Type "about:config" into the address bar and hit Enter. Click the button "I accept the risk!". Type media.peerconnection.enabled in the search bar. Only one entry should appear. Right-click on the entry and choose "Toggle" to change the Value column to "false".
To enable WebRTC again, follow the instructions until the Value column changes back to "true".

WebRTC in Mozilla Firefox is supported since Firefox 22, and it's enabled by default.

To disable RTCPeerConnection and protect IP addresses leakage, go to about:config and toggle media.peerconnection.enabled to false. <>p>To disable Media Devices, toggle media.navigator.enabled as well as media.peerconnection.enabled both to false. </details> # Some sources
