Simple Link Checker автор Francesco De Stefano

Check Links is an add-on developed primarily for web designers, developers and content editors.
It quickly finds all the links on a web page, and checks each one for you. It highlights which ones are valid, which ones are redirect, and which ones are broken, simple as that.

A new version is being implemented and subjected to different tests ... Time available permitting :). Therefore I apologize in advance for any delays.
