Do the WebRTC leak test again.</li> </ol> <p>If you want to make sure every single WebRTC-related setting is really disabled change these settings:</p> <ol class="long-string-list"> <li>media.peerconnection.turn.disable = true</li> <li>media.peerconnection.use_document_iceservers = false</li> <li>media.peerconnection.video.enabled = false</li> <li>media.peerconnection.identity.timeout = 1</li> </ol> <p>Now you can be 100% sure WebRTC is disabled.</p> <p> <a class="btn btn-primary" target="_blank" rel="noopener noreferrer" href="https://ipleak.net">Test your Browser again</a> </p> <h3>How to fix the WebRTC Leak in Google Chrome?</h3> <p>WebRTC cannot be fully disabled in Chrome; however, it is possible to change its routing settings (and prevent leaks) using an extension. Two open-source solutions include <a href="https://chrome.google.com/webstore/detail/webrtc-leak-prevent/eiadekoaikejlgdbkbdfeijglgfdalml">WebRTC Leak Prevent</a> (options may need to be changed depending on the scenario), and <a href="https://chrome.google.com/webstore/detail/ublock-origin/cjpalhdlnbpafiamejdnhcphjbkeiagm">uBlock Origin</a> (select "Prevent WebRTC from leaking local IP addresses" in Settings).</p> <h3>What about other browsers?</h3> <p>Chrome on iOS, Internet Explorer and Safari does not implement WebRTC yet. <a href="#browser"><i class="fas fa-link"></i> But we recommend using Firefox on all devices.</a></p>
