READ THE REVIEWS -- I do not remember it asking for permission to change anything so if it asked for any home page or browser changes it did so stealthily. I didn't recognize the search engine, but it appears connected with Yahoo. I've gotten Yahoo connections on other unaproved add ons from the Firefox collection in the past. A Firefox dialogue warned me that the new tab setting had been changed. I may not be the sharpest tech tool in the Mozilla shed, but I'm not the dullest. If they fooled me out of about 7500 users, then there are too many others fooled as well.
