What is the easiest way to validate page references? (css, javascript, etc..)

i've got firebug (my team does not have firefox), and the IE developer toolbar(IE7) but I can not seem to figure out how to easily validate if the referenced 开发者_JS百科files in a page are loading (i see javascript errors, but that doesn't succinctly point me to the exact file in a heirarchy of jquery - jqueryUI - datepicker files).

Additionally i'd like to be able to do this remotely, because on our corporate domain some files load fine for me, but not anyone else because they sometimes get encrypted to my domain user. So it would be nice if this process was either simple enough for my teammates to do it very quickly, or ... even better somehow with automation from a remote machine or web service request.

I thought I had seen a simple place on firebug to validate what loaded and what did not, but I can't find it now.

What are my options?

do you tried Javascript Lint? Or the javascript plugin for Eclipse.

do you know YSlow?

It provides you with a set of excelent tools for web developing and I think it solves your question
