If you are having a hard time making your POST requests to work (like I had with a login form), it definitely pays to quickly install the Live HTTP headers extension to Firefox (http://livehttpheaders.mozdev.org/index.html). This small extension can, among other things, show you the exact POST data that are sent when you manually log in.

In my case, I had banged my head against the wall for hours because the site insisted on an extra field with 'action=login' (doh!).
