fyi for folks doing spdy/3 that want to test interop, I checked in
spdy/3 support for firefox yesterday.
You can get a nightly (firefox 15) at
http://nightly.mozilla.org/ . It
is disabled by default for the next 10 days or so until we start a
firefox 16 - then I'll turn it on by default assuming it all goes well
at first. If you want to turn it on to test with just set
network.http.spdy.enabled.v3 to true in about:config
