HTTP/3 doesn't work regardless of my config:

network.http.http3.enable = true network.dns.httpssvc.http3_fast_fallback_timeout = 0 network.http.http3.priority = true

and https://cloudflare-quic.com/ and console still show I'm using HTTP/2. Tried on Firefox nightly and chromium (chromium works fine but firefox doesn't.)

I see HTTP/3 requests on www.cloudflare.com, both on Nightly and release (117.0.1) with HPPT/3 enabled , but not on the cloudflare-quic.com site.

I did some more investigation and testing and see some HTTP/3 requests on https://cloudflare-quic.com/.

Only https://quic.tech:8443/ and https://quic.rocks:4433/ work and I have to refresh the page to get it work.

Cloudflare and rest of the sites are still using HTTP/2.
