Google Chrome
Using Chrome Flags (Limited Control):
- Open Chrome and type chrome://flags in the address bar. Press Enter.
- Search for "WebRTC" in the search bar.
- Locate the flag labeled "WebRTC STUN origin header".
- Click the dropdown menu next to the setting and choose "Disabled".
Important Note: Disabling STUN can limit some WebRTC functionalities on websites. It might prevent features like video calls or screen sharing from working properly.
Using Extensions (Consider with Caution):
It’s best to use an extension to disable WebRTC on Chrome here are a couple of extensions you could use:
WebRTC Network Limiter is an official Google extension that tinkers with WebRTC settings to stop any IP leaks without completely blocking it. Since WebRTC Network Limiter doesn’t completely block WebRTC, the services that use WebRTC will still work on your browser.
uBlock Origin isn’t dedicated to WebRTC alone, but it has a feature to disable it on your browser.
WebRTC Leak Prevent is the leading Chrome extension for preventing WebRTC leaks. As the developer has noted, this extension only changes WebRTC’s security and privacy settings – it doesn’t turn WebRTC off.
Mozilla Firefox
Using Firefox Configs :
- Type about:config into your address bar and press Enter. Click the Show All button.
- Toggle media.peerconnection.enabled to false.
- To disable media devices, toggle media.navigator.enabled to false.
- Retest for WebRTC leaks to make sure the issue is resolved.
Microsoft Edge
Using Edge Flags :
- Open Microsoft Edge.
- In the address bar, type about:flags and press Enter.
- This opens the developer flags settings. You might see a warning message; you can safely ignore it.
- In the search bar, type WebRTC.
- Look for the setting labeled "Hide my local IP address over WebRTC connections".
- Click the dropdown menu next to the setting and choose "Enabled".
- Once you've made the change, click the "Restart" button at the bottom of the page to apply the new settings.
- By enabling "Hide my local IP address over WebRTC connections," you prevent WebRTC from revealing your true IP address to websites. This helps maintain a layer of privacy while still allowing WebRTC functionality if needed by certain websites.
