VPN and Firefox IP leak risks
VPN and Firefox IP leak risks
So I recently discovered the hard way that Firefox enabled DNS over https which caused ip leaks. Not sure if this is a common issue or if it's been posted before but the fix is to go to preferences >network settings>DNS over https and disable it. Hope this helps someone avoid frustration because I thought I messed up in the order I turn my VPN to play games.
A "WebRTC leaks" refers to unauthorized data exposure when using WebRTC's STUN protocol, which can reveal public IP addresses. To turn it off, adjust settings in Mozilla Firefox, install the Chrome extension, or modify Opera and Windows configurations as described.
"DNS leaks" occur when unencrypted DNS queries are sent outside a VPN tunnel, exposing your system to external monitoring. This happens because Windows doesn't manage a single global DNS, allowing each network interface to use its own DNS settings. The svchost.exe process may send queries without following the VPN's routing table or default gateway.
Should you be concerned? Yes, if your ISP or others could track your browsing activity by seeing the domains you visit. Prevent leaks to protect your privacy, especially in regions with restricted rights.
WebRTC is unrelated to DNS. DNS-over-HTTPS remains unencrypted and isn't transmitted beyond the VPN tunnel unless your setup is incorrect.
