Nice Rated 5 out of 5 stars
This is really great to see the W3C features implemented (as I think it should be within Firefox) and in a logical and apparently comprehensive way. For anyone who gets this extension, I also recommend https://addons.mozilla.org/en-US/firefox/addon/1386 to allow you to pick alternate stylesheets from a page--also a feature (I put them all in one toolbar as the other extension also has a "css" toolbar drop-drown).This review is for a previous version of the add-on (1.5).
