In the case of browsers where WebRTC can’t be
disabled, you need to use
third-party browser add-ons or extensions to solve the problem. If you
use Chrome, download uBlock Origin or use the available Chrome
extension. It is the same solution for Opera although use the Opera
extension and not Chrome's. Or you can change to a VPN service like
ExpressVPN that have a built-in rule. I must say - stay away from free
VPN services. Why? Well, even if you do all the browser set-ups the data
that you still provide will be used on a commercial basis and sold.
By the way - even mobiles (Android) suffer from this so do the same for your mobile!
everyone ought to use a VPN (Virtual Private Network), and in doing so,
hide your real IP address and even come from a different country. There
can be some interesting quirks that if you do change to a 'foreign'
server you can get replies and websites in their language. But I find
generally speaking that this is rare. Have fun.
