Ok, Calvin points out one great point: if you are trying to support someone remotely on a bug, you can get them to record their XML log and send it to you. Thats cool. However...
Web Applications are more than just GET/POST these days. By the time you factor in AJAX, maybe Flash(/Laszlo/Flex) there are a lot more parts to doing a regression test than just the GETs and POSTs.
Firefox is used as the test tool too..
Once you record and serialize to xml, you can replay and use the same extension as your test bed, in that sense, Firefox is your test tool.
