ADWARE AND SPYWARE IN THE ADD-ON Rated 1 out of 5 stars
This add-on includes so called "price comparisons and coupon alerts". Obviously, this thing has nothing to do with the primary goal of this add-on. Integration into amazon leads to a huge security risk: nobody can say, how they process requests from your browser on their server.
There are many other screenshot add-ons for Firefox. If you care about your account security and privacy, don't install this add-on.
