NuCheck od cisco211

Simple extension that provides buttons to copy the HTML source of the current tab and opening the Nu Html Checker website, where you can directly paste in the HTML source in your clipboard.

It has 3 buttons:
Copy HTML: Copies the HTML source of your current tab into your clipboard.
Open Validator: Opens the Nu Html Checker website.
Copy & Validate: Does both things at once.

Using this extension, the HTML validation simplifies down to just one mouse click and a paste (Ctrl+V / Cmd+V).

I wrote this extension because the good old "HTML Validator" extension is somewhat outdated. I need a modern solution that makes that HTML validation checking work as convenient as possible.
