More specifically I'm looking for something, perhaps an add-on for firefox, once enabled it logs all of this information as it's passed to and from the server. I'm doing some web scripting and this would be really handy.

If anyone is wondering specifically what I'm doing currently I'm trying to make a script to repost my craigslist ad every 2 days since I handle a few things on there. Might even go so far as to make a simple gui to manage the submissions.

I do suspect this goes against the ToS, for that reason I don't plan to release the code. Besides cl is already bad enough with spam, I'm not trying to contribute further to it, figured I'd say what I'm doing for the sake of being honest though. I don't have any bad intentions with this, just some things I've been trying to sell an ad for my pc repair business. I've been reposting some things for months now and so often I just forget to do it.
