I visited https://cloudflare-quic.com/ and it said my browser used HTTP/2 when loading that page. Devtools also said is load with HTTP/3 protocol. `network.http.http3.enabled` is true in about:config

Turns out is because `network.dns.disablePrefetch` is true, by setting that to false fixed the issue.
