HTTP/2 for Firefox is currently under development.

As of Jan 18 2014, HTTP/2 draft support is included in routine builds of the nightly firefox-29 channel. It is disabled by default.

To get the nightly channel, download from https://nightly.mozilla.org/

To enable, go to about:config in the location bar and set network.http.spdy.enabled.http2draft and security.ssl.enable_alpn to true

The current implementation is of draft-09 and compression-05.

Firefox will only be implementing HTTP/2 over TLS - and right now that means for https:// schemed URLs. It does enforce the protocol's >= TLS 1.1 requirement - if a server negotiates HTTP/2 with a lower TLS version it is treated as a protocol error. (there is a preference for changing that for testing purposes if you need it.)

This build supports basic push and continuations and both alpn and npn.

feedback of any sort welcomed to pmcmanus@mozilla.com and hurley@mozilla.com

There is a separate, more experimental, build available that supports HTTP/2 for http:// URIs using Alternate-Services and the "h2t" profile. This allows HTTP/2 over TLS for http:// URIs in some cases without verification of the SSL certificate. That code is at
