Must have add-on Rated 5 out of 5 stars

Web of Trust is an essential tool if you surf a lot of different webpages. Many times I've thought I'd sign up to a mailing list only to read the reviews on WOT and decide not too.

It is especially important for designers using Google images.
It even lets you know if Twitter links are suspect.
It should be an auto-download.

This review is for a previous version of the add-on (20110704).
