I believe Firefox on Linux uses libc call (in my basically default
setup).  When I enable logging, I get:
> [...] D/nsHostResolver DNS lookup thread - Calling getaddrinfo for
host [...]
I haven't dug too deep, perhaps they use
https://developer.mozilla.org/en-US/docs/Mozilla/Projects/NSPR/Reference/PR_GetAddrInfoByName

Please, correct me if I'm wrong.

Of course, DoH has an advantage in this respect, but I don't expect most
of dnsop wants to push browsers that way...
