Firefox turns controversial new encryption on by default in the US
Mozilla is motivated in part by ISPs who monitor customers‚Äô web usage. US carriers like Verizon and AT&T are building massive ad-tracking networks. DoH won't stop the data collection but it‚Äôll likely make it more difficult.
Although it‚Äôs much harder for others to see your DNS lookups with DoH enabled, the websites will still be visible to the DNS server your browser is connecting to. Thus, Mozilla says Firefox will offer a choice of two trusted DNS providers, Cloudflare and NextDNS, and that Cloudflare will be used as the default.

The problem here, brothers, is that your internet provider may be spying on you, using the information coming thru Google or the actual pages you visit. They apparently will use that information to shower you with ads related to what you must be interested in.
