Measure the time Firefox needs for rendering a page and evaluating JavaScript and CSS

Is it possible to measure the time Firefox needs for rendering a page and evaluating all the JavaScript and CSS sources? I tried it with Firebug, YSlow and Google Page Speed but none of them satisfied my specific needs.

I need this 开发者_StackOverflow中文版for profiling a customer's web pages. But I have no idea how to do this. It seems to be possible in Chrome ("Timeline" tab in developer tools"). But I guess Chrome (I have version 10) should be much faster than Firefox 3.6. so it's no valid reference system for my measurements.

Can someone help me out?

Firebug is as good as you are going to get, you could try this:

I heard about it on a Google Tech Talk with a guy from Edmunds - very good

I use dynaTrace AJAX Edition. It works with Firefox and IE. It is an advanced profiling tool. http://ajax.dynatrace.com/ajax/en/
