neat idea Rated 5 out of 5 stars
This is a neat idea, and not deserving of its place on PCmag's list of the 10 most useless Firefox extension (http://tinyurl.com/2n5ze3), because the visual clues do help to orientate yourself on the page.
One problem though: the results page often gets rather jagged because many sites don't have an icon, so it would be good if the white default icon or empty space was put in its place.
EDIT: I just noticed after an add-ons update that the you've added default icons. Thank you very very much! Upgraded my rating to a perfect 10. :)
