(Don’t mention Dust-Me Selectors, because that doesn’t work with Firefox Beta 4.

I’m planning on doing a refresh of my website’s layout, coding-wise. Removing old CSS classes, using ID’s instead of classes where needed, validating content, etc. etc. I’d rather not have to spend time "checking off" CSS classes if at all possible.
(I did recall that extension I mentioned allowing for a sitemap file to be used instead of viewing every page, so if that’s the case, if someone who has Firefox2 could run that for me, I’d be grateful. I would like to have a script to do it myself, though...)
