Fine. Rated 4 out of 5 stars

This thing works okay, but doesn't notify you if a site is a suspected phish - one that has been reported, but not yet verified. In these circumstances, the native phish checker in Firefox must be relied upon, making the Phishtank Site checker somewhat redundant, because what it catches, the default filter probably does, too. Additionally, it lacks a professional feel, such as when it displays messages like "Okay, you are going back to the safe zone now".

This review is for a previous version of the add-on (4.0.9).
