[PD] Pd-extended and Firefox

using JACK is the best way to go in terms of performance and low 
latency. If you don't care about latency in Pd and don't want to muck 
with settings, you can just do:

aoss pd -oss

and everything will cooperate together, with something like a 200ms 
latency in Pd.

Previously I tried using JACK as the backend for pulseaudio as Pedro is 
suggesting. It works pretty well except that it was set up on my laptop 
and things would get screwy after my laptop would wake up from 
hibernation. I'm sure that's solvable but at the time I gave up after 
spending too long playing with hibernation scripts trying to solve it 
and achieving inconsistent results.
