Track each URL and Parameters sent from Form

Question

Simple question really for anyone who's been through this:

I have a form that I'm placing on a site. This form submits some parameters to a site which then sends some parameters using "GET" to another site, which then opens the third site.

Now the first 2 sites pass so quickly that I can not see what parameters were passed using the URL. I can do a manual check using source code but its too long and complex.

I just need a simple tool or hint or firefox addon on how to track every single URL (wven if it has a META redirect) so I can read parameters being sent via the form.

Thanks
