Finally, Firefox is going to have support for Google SPDY. Firefox 11, currently in beta channel, has first implementation of SPDY which brings responsive page loads and scalability for the real time web.
According to Mozilla, “The most important goal of SPDY is to transport web content using fewer TCP connections. It does this by multiplexing large numbers of transactions onto one TLS connection. This has much better latency properties than native HTTP/1. […] web pages on high latency connections with high numbers of embedded objects will see the biggest benefit from SPDY.”.
SPDY is a networking protocol being developed by Google, and its acceptance has increased recently. The chairman of HTTP Working Group has also announced to include it in the HTTP 2.0 standard.
By default, SPDY is currently disabled in Firefox 11. To enable it, users need to set network.http.spdy.enabled preference to true through the about:config page.
