DoH disabled by default in Firefox on OpenBSD reddit / BSD ---------------------------------------------------------------------- ubuntufig · 2019-09-13 22:30 Hope the others follow ---------------------------------------------------------------------- [deleted] · 2019-09-18 17:19 Disabled is a better default. If you are dealing with systems where the default is enabled then blocking is fairly trivial since firefox ships with only one DoH server in its config. Return a non-routeable address for cloudflare-dns.com and block outgoing packets to 1.1.1.1.
