Starting today, Mozilla is activating the DNS-over-HTTPS security feature by default for all Firefox users in the U.S. by automatically changing their DNS server configuration in the settings.

That means, from now onwards, Firefox will send all your DNS queries to the Cloudflare DNS servers instead of the default DNS servers set by your operating system, router, or network provider.

The way Mozilla implemented DNS-over-HTTPS in the Firefox web browser also received criticism over in past few months over favoring Cloudflare and instead of trying to upgrade to an encrypted DoH server operated by the user's existing DNS provider.

On the other hand, Google took care of this privacy issue while announcing DNS over HTTPS feature in its Chrome web browser late last year, which automatically upgrades DNS settings to the equivalent DoH service from the same provider if it's DoH-compatible.

Any Firefox user, outside the U.S. or US-based, can also manually turn on this feature from Firefox settings and can change the default DNS server to NextDNS or any other encrypted-DNS service by manually entering the address.
