DNS over TLS has other issues. There's a nice comparison there https://dnscrypt.info/faq/ I have been using local resolver on 53, that forwards all requests from my LAN into DNSCrypt (and sends that over a VPN tunnel). That way I maintain privacy, and decentralization as well as being able to simply use the DNS resolver built into my OS.
The IETF QUIC isn't finished. Periodically the Working Group thinks it has stopped fiddling with the low-level bit layout and is ready to focus on polish, then somebody finds a show stopper that means revisiting the low-level bits. Maybe 2020? They missed all their advisory target dates (July 2019) for actually writing documents, and that isn't the end by any means for a protocol like this.
So Firefox could at most support either Google QUIC (internal prototype, now obsolete, who cares?) or a random draft that may end up not resembling the final product. If they haven't decided to do either it doesn't seem like a big deal.

Ah yes you're right. Also Mozilla (M. Thomson, Ed) is on the author list there so I expect they will support it when it is finalized.
Hopefully then they also support DNS over QUIC, I expect they probably will once QUIC is finalized. I think DoH is just a stop-gap measure to be honest.

I have to wonder though with HTTP/3 https://en.wikipedia.org/wiki/HTTP/3 being QUIC based, will we see DNS over QUIC? https://en.wikipedia.org/wiki/QUIC
Seems like Firefox doesn't even support QUIC at the moment. https://bugzilla.mozilla.org/show_bug.cgi?id=1158011
