DNS over HTTPS (DoH)
When we search websites on the internet our DNS communication is insecure meaning our employer, ISP, and Country we live in can monitor which websites we visit. WIth DNS over HTTPS (DoH) we can now secure the transport of our DNS queries directly to our preferred DNS server.
Firefox is the first browser to implement DNS over HTTPS (DoH). Check out how to setup DoH and check your other browsers to see how secure they are. I don't see Chrome adding this feature anytime soon but possibly Safari would as they are more security conscious.
