Decent -- Except for the CRAPWARE Rated 3 out of 5 stars

Authors state: "This extension also integrate some additional features such as 'Discover Similar Sites' and 'Price Comparison While You Shop.' These are value-added features, and definitely are not "Malware" or "Adware" as some may mistakenly believe."

Bull!!! It is definitely a form of Adware. And it is definitely CRAPWARE. The screenshot extension itself is good but will not get more than 3-stars from me until the additional CRAP is removed.

This review is for a previous version of the add-on (2.4.0.1).  This user has other reviews of this add-on.
