DNS stands for “the Domain Name System” – a protocol that makes sure any numerical IP addresses are “translated” into a global and worldwide human-readable directory service. In fact, the DNS has been described as “the phone-book of the internet.”

Firefox now implementing DNS over encrypted and secure HTTPS (DoH) by sending DNS requests via the encrypted HTTPS protocol.

You can enable or disable DoH in your Firefox connection settings:
