Let us for a minute assume that there is nothing wrong with FF. How about installing Firebug and see in the "Net" tab that what precisely is happening when you load the Twitter main page? Is it waiting for apparently no reason at a particular place? Also, not strictly required, but can you also pass the traffic through something like LiveHTTPHeaders and post a traffic dump? As a third step, run a "pcap" session and see what is happening on the wire/air ?

This probably means that none of the "advanced" rendering stuff work on your X setup.

This is a completely distinct problem but probably it would be interesting to try and figure out why Graphics Acceleration is not working. I have very limited experience with Intel Graphics chipsets. In the i915 days, there used to be something called AIGLX which required some explicit configuration in xorg.conf. Could you check on that?
