Firefox fixes. + support for more than one initial packet + workaround for trailing zeroes in packet + ignore application data packet if no keys yet (issue in draft 27/ff nightly) + fixed PING frame parser + STREAM frames need to be acknowledged The following HTTP configuration is used for firefox (v74): http { ssl_certificate_key localhost.key; ssl_certificate localhost.crt; ssl_protocols TLSv1.2 TLSv1.3; server { listen 127.0.0.1:10368 reuseport http3; ssl_quic on; server_name localhost; location / { return 200 "This-is-QUICK\n"; } } server { listen 127.0.0.1:5555 ssl; # point the browser here server_name localhost; location / { add_header Alt-Svc 'h3-24=":10368";ma=100'; return 200 "ALT-SVC"; } } }
