FireBug Ajax/DHTML Debugging Tool for Firefox
It’s brand-spankin’ new (and the developer owns up, calling it a “pre-pre-pre-alpha release”), but man the FireBug extension is right handy.
Some initial caveats:
Some users report the XMLHttpRequest Spy feature works fine when using the Prototype library but apparently maybe not so much when using roll-your-own XHR functions.
While the dev says FireBug “only shows you errors and log messages that came from the page you’re looking at,” I noticed today that is not necessarily so. I was working with pop-ups, so it could be this early version gets confused when dealing with child windows. I didn’t get all empirical with it, so your mileage may vary.
