In nightly builds<\/a><\/noindex> Firefox, which will form the basis of the Firefox 72 release scheduled for January 7, has added<\/a><\/noindex> support for the HTTP\/3 protocol. By default, HTTP\/3 is disabled and requires activation of the option 'network.http.http3.enabled' in about:config. <\/p>\n

HTTP\/3 support in Firefox is based on a project developed by Mozilla neqo<\/a><\/noindex>, which provides an implementation of the client and server for the QUIC protocol. The code for the components supporting HTTP\/3 and QUIC is written in Rust.
\nExperimental support for HTTP\/3 is also already available in has added<\/a><\/noindex> Chrome and curl, and for servers, it is available in the form of a module<\/a><\/noindex> for nginx and a test server<\/a><\/noindex> based on the library quiche<\/a><\/noindex> (implementation<\/a><\/noindex> of QUIC and HTTP\/3 written in Rust by Cloudflare). To test HTTP\/3 clients, several test websites have been launched, most of which do not yet open correctly in Firefox (HTTP\/3 is in the<\/a><\/noindex> draft specification and is not yet standardized).<\/a><\/noindex> In the nightly builds of Firefox, which will form the basis of the Firefox 72 release scheduled for January 7.<\/p>\n

It should be noted that HTTP\/3 standardizes the use of the QUIC protocol as a transport for HTTP\/2. The protocol QUIC<\/a><\/noindex> (Quick UDP Internet Connections) has been developed by Google since 2013 as an alternative to the TCP+TLS stack for the Web, addressing issues with long connection setup and negotiation times in TCP and eliminating delays when packet loss occurs during data transfer. QUIC is an extension of the UDP protocol, supporting multiplexing of multiple connections and providing encryption methods equivalent to TLS\/SSL. <\/p>\n
