How to Disable WebRTC on Browsers

WebRTC allows you to make video calls through your browser, among other features. However, it can also be a privacy leak that can cause your data to be exposed, even while using a VPN.If you’re not using your browser for video calls anyway, it is highly recommended to disable WebRTC on your browsers so as not to undermine your VPN.

Note that if you have various browsers that you use on a regular basis, it is imperative that you disable WebRTC on them all! This will make sure that using a specific browser won’t leak your private information.

Here are the steps to disable WebRTC on different browsers:

Google Chrome and Microsoft Edge

Due to the way these browsers are created, you cannot disable WebRTC directly from within their settings. Instead, you can use extensions to achieve the same.

One of the most common extensions used for this purpose is uBlock Origin (Chrome, Edge). This app not only blocks WebRTC, but also ads and malicious connections that can make their way through your browser. Because of this, it’s a must-have for every privacy-conscious internet user.

Note that even such extensions aren’t always 100% effective. If this can cause problems for you, it’s recommended that you switch to a different browser that allows you to disable WebRTC directly.

Mozilla Firefox

Firefox is built as a privacy-respecting browser, so it takes only a few clicks to disable WebRTC:

STEP 1. On the address bar, type about:config and press Enter. Click Show All. Note that if this is your first time entering the browser’s config settings, you may receive a prompt that asks you to turn back. Proceed anyway.

STEP 2. Look for media.peerconnection.enabled and click the toggle button to make the value false.

STEP 3. Look for media.navigator.enabled and click the toggle button to make the value false.

STEP 4. Do another VPN leak test to check that the leak has been patched.

Apple Safari

STEP 1. Click the Safari button on the upper-left, then go to Preferences.

STEP 2. Click Advanced, and check the Show Develop menu in menu bar tckbox.

STEP 3. Click Develop in your menu bar, beside Bookmarks. Look for the WebRTC drawdown, and uncheck the Enable 2Legacy WebRTC API. If you find that this option is grayed out, then that means WebRTC is already disabled.

STEP 4. Try another VPN leak test to make sure you’re browsing in anonymity.

Opera Browser

Much like Firefox, Opera was conceived as a privacy-respecting browser. The process to disable WebRTC is even more intuitive:

STEP 1. On the address bar, type about:config and press Enter.

STEP 2. Go to Settings then click Advanced > Privacy & Security. Look for the WebRTC option. Here, check Disable non-proxied UDP and save.

STEP 3.  Run the VPN leak test again to make sure the fix worked.
