1195456 - Log HTML validation errors ( optionally )

Status: NEW

(DevTools :: Console, enhancement, P4)

Description

[Jeff Griffiths (:canuckistani) (:⚡︎)]

As a developer I need to at least be able to enable and check html validation errors in my page.

Related uservoice: 

"The very first step in debugging is to be sure that there are no initial errors, so it would be great if Firefox could optionally log HTML validation errors as the page loads, or upon validation request.
Just like JS and CSS errors are now logged to the console, HTML could be logged in the same way, or like the HTML validator does (http://users.skynet.be/mgueury/mozilla/) but without external requests if the page has a HTML5 doctype."

I wonder if that's something that could go in a more useful panel, in the inspector or the application panel.
