It stopped working. They must remove it from the Chrome Web Store.

Works fantastically, speeds up my validation workflow by an order of magnitude

Getting "The character encoding was not declared. Proceeding using “windows-1252”." for all websites. Particularly, mine does declare UTF-8

مفيد جدا يكتشف الاخطاء التكويدية الخاصة بالصفحة بدلا من رفع الصفحة على الانترنت واعتماد الصفحة ان ليس بها اخطاء

Doesn't work. Complains about character encoding not declared. But it is declared and W3-Validator shows no problems. So: Useless Extension

the instruction are outdated/faulty, after "icon-click" it opens only menu, no validation at all...

Lacks an option to ignore certain error/warning types which is important since the official validator flags errors for non-standard attributes which are still VALID under HTML 5. Makes the results very hard to use for anyone using AngularJS or similar on their site.
