I'm not sure if I have followed all of the discussion. But if your
problem is to record firefox, it's not very difficult:

1. Start jack

2. Start pulseaudio using jack sinks:

       $ pulseaudio -L module-jack-sink -L module-jack-source

    [Automatically: Put "'sleep 5 && 
/home/kjetil/bin/startpulseaudio.sh' &" under 
qjackctl->options->"execute scripts after startup",
     where "startpulseaudio.sh" is a script containing "pulseaudio -L 
module-jack-sink -L module-jack-source"]

3. Start firefox

4. Play something

5. Record from jack, for instance using jack_capture, like this:

       $ jack_capture

    (no options!)
