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?
