Modern Network Protocols — What’s Next for Firefox and the Web?
H.1302 (Depage) | Day 1 | 11:20 - 11:40 | Speakers: Max Inden, Andrew Creskey
Abstract
The Web’s transport stack is changing rapidly, with QUIC, HTTP/3, and encrypted DNS seeing broad adoption. This talk gives an overview of the modern network protocols Firefox already deploys and invests in, including QUIC and HTTP/3’s growing share of Web traffic. It will highlight what Firefox actually sends on the wire today, what benefits we observe in practice, and where the Web’s protocol landscape stands in early 2026.
The session will also offer an outlook on what’s likely to land in Firefox and across the Web in 2026 and beyond. This includes emerging mechanisms like Happy Eyeballs v3 to manage increasingly complex protocol selection, WebTransport as a modern WebSocket primitive, MASQUE-based proxying for new tunneling use cases, and ongoing work around encrypted DNS, resolver discovery, and Encrypted Client Hello. Together these protocols form the foundation of a faster and more private Web.
