Rated 5 out of 5 stars

Really nice tool! It helped to find errors on my web-site that I was even aware of.
To developer: it would be great if it was en option to have some kind of pop-up window that shows after the check with statistics. Because sometimes it's tricky to look for broken link on a long and complicated page, even if they are highlighted.
.. And thank you so much for this tool!

This review is for a previous version of the add-on (0.6.6).
