Validating web page
This extension helps to validate a web-page using a validator created by Philip Walton.
This will be a useful tool when it comes to checking pages create follow HTML standards. This is especially useful for accessibility(ARIA attributes) and cleaning up un-used markup.
Usage : Open the developer tools, goto Console. Click on the extension on the browser. All the errors/warning will be shown on the console.

Doesn't seem to support HTML files or localhost addresses, which would make it useless for development.
Simple and easy to use.
