Firefox Extensions For Web Professionals
(Discovery #1 – HTML Validator)

Today’s discovery is HTML Validator ( http://users.skynet.be/mgueury/mozilla/ ). This add-on validates web pages to the W3C HTML standards with a simple green check in the corner of the page if the page validates, a red check if it doesn’t, and a yellow exclamation point if there are warnings. It also includes an enhanced view of source code that allows you to see where errors are within the code.

To install (add-on), from within Firefox:

• Tools > Add-ons > Get Add-ons > Search "HTML Validator"

and select the add-on from the list.
