Following OpenBSD's lead [1], RHEL and Fedora will [2] disable DoH by default in Firefox for privacy reasons. I believe we should do the same in Arch, since it does really not sound like a good idea to centralize all DNS queries to a single US-based company, and interested users can still opt in if they wish so.
Technically, it would mean setting network.trr.mode to 5 by default, as described in [3].

This task depends upon

Reading [3], a value of 0 actually acts as 5, that's no different in behaviour.

network.trr.mode=0 - Off (default). use standard native resolving only (don't use TRR at all)
network.trr.mode=5 - Off by choice. This is the same as 0 but marks it as done by choice and not done by default.

Where is the issue?
