Firefox extension that tells you the CSS rules that are not applied within your page, set of pages or complete website. And from a reputable website, Sitepoint.

I have not tried it completely yet, but it can only help.. it can spider your entire site, as well as just single pages.

Nice idea, but what about dynamic elements?

My main work site is mostly AJAX, but I also coded so someone without javascript can still use it... dustmeselectors seems good to me!

You are right though, if your site won't work without js, you won't find it as useful

Chrome's debugger will also do the same with a little bit of sleuthing. and while ajax is running.

The advantage of the Firefox add-on is that it can spider your site, and so get a list of all CSS that is redundant - I suppose a combination of that & Chrome would do it.

Or we can await the Chrome plugin!
