+/* 0720: disable DNS-over-HTTPS (DoH) [FF60+]
+ * DoH is currently only being rolled out to US users who are prompted to opt-in
+ * 0=off by default, 2=TRR first, 3=TRR only, 5=explicitly off : TRR = Trusted Recursive Resolver
+ * [NOTE] removed in FF69; 1=race, 4=race for stats but always use native result
+ * [THORIN] I don't tell users how to connect to the internet, how to configure proxies, what
+ *   search engines to use; these are all subjective and depend on your setup / threat model.
+ *   Likewise, I am not interested in providing, maintaining and supporting a DoH section
