Top add-on Rated 5 out of 5 stars
Such a great add-on, right up there with Firebug and Web developer extension as essential add-ons. The new OpenSP validator as used by the w3c validator is a fantastic new addition.
Certainly alot easier to use than installing the w3c validator on a windows dev machine. Keep up the great work.
