Just an fyi. DoH is a fucking nightmare for network management. For example, if you use a pihole on your network, you 100% do NOT want devices using encrypted DNS.
I meant Cloudflare DNS, I don't understand why Firefox uses Cloudflare DNS when there are so many other great options like NextDNS. The reason why many people in the privacy community dislike Cloudflare or CDNs in general is because they are often hostile to VPN or TOR users, and they centralize the web.
