I wish there were more tools for Firefox 11 and SPDY, absolutely no way to tell what is going on.

But I guess the beta and SPDY support is far too young for now.

The only indicator I have is the response headers will add

   X-Firefox-Spdy: 1

...which I see on Google services and now twitter.

I guess someone could write an extension to watch the response headers and show an indicator.

Here's a version for Firefox: https://github.com/chengsun/moz-spdy-indicator

Impressive, many thanks - I was reading up on how to use visitResponseHeaders but you saved me a bunch of time.

Is that you in the top three Google Code-in 2011 Grand Prize Winners? I guess we can look forward to great things from you over the years.

Yep, that was me :) I worked on better integration of VLC plugin in browsers on Linux; that was a lot of fun.

Thanks! I guess I can now rm -rf moz-spdy-indicator my work-in-progress. :)

chengsun: in indicator.js, what is the lifetime of SPDYObserver.cache? SPDYObserver.observer() saves every URL in the cache, but never flushes old URLs from the cache.

I was concerned about that as well. I just rewrote the observer to store data with the tab instead of in the cache indefinitely.

It's open source so you don't have to trust his word: https://github.com/guille/chrome-spdy-indicator

Welp, it's an addon that has to interface with every tab in order to do its job, i.e. tell you if SPDY is in use. What exactly are you asking for?
