So, you have three machines, A, B and C. You're on A, you ssh to B to
run Firefox on C? It's not really clear. Could you give an example
series of ssh commands on each of the machines to do what you're
describing?

My question would be, how are you verifying that Firefox's HTTP
requests are coming out of the machine the X server is running on? (I
take it that's the behavior you're seeing.)
