WebRTC is a technology that is used to deliver communication capabilities such as video chat, screen sharing and some other really cool stuff.
But in order to do that well, it also digs into your system internals to pull and reveal your actual IP address, even if you are using a proxy or a VPN. That means that simply having WebRTC enabled in your browser – even if you are not using one of those fancy communication apps – leaves you vulnerable to WebRTC leaks of your real IP address.
It essentially renders your proxies useless.
To fix this you can disable WebRTC in your browser. But solutions for doing this in Chrome, for example are not always effective, so we’ve dug into the browser internals to give you more reliable options for doing this.
Disabling WebRTC in Ghost Browser means you not only prevent the leak of your real IP address when using proxies, but it also hides your ‘media device ID’ so that list of IDs can’t be used to make a fingerprint of your device.
To block WebRTC go to Menu –> Settings –> Advanced –> Privacy and toggle the switch to ‘Disable WebRTC’. This means that you won’t be able to some apps that use WebRTC for browser based collaboration – but it will protect your privacy and prevent tracking.
