2059947 - Enable QUIC v2 version negotiation on all channels

Status: RESOLVED FIXED

(Core :: Networking: HTTP, task, P3)

Description

[Max Inden]

network.http.http3.version_negotiation.enabled has shipped as Nightly-only (@IS_NIGHTLY_BUILD@) since it was introduced. When the pref is true, neqo offers Version::all() (QUIC v2 preferred, then v1), so Firefox can negotiate up to QUIC v2 (RFC 9369) with servers that support it; when false it offers QUIC v1 only.

The pref has ridden Nightly without issue. Time to enable it on all channels by setting the value to true.

Pref: https://searchfox.org/mozilla-central/search?q=network.http.http3.version_negotiation.enabled&path=StaticPrefList.yaml
RFC 9369 (QUIC Version 2): https://www.rfc-editor.org/rfc/rfc9369.html
