Perhaps you should run a packet sniffer while Mozilla / $other_working_program do their thing, and see what those programs send in order to work. Ethereal seems pretty popular, though I prefer ngrep because it doesn't need any fancy X GUI which makes it handy to run on servers and remote machines, which is where you're most likely to need a sniffer anyway.
