After a purchase from a legitimate retailer, I got a false offer to get $40 credit if I installed this browser extension. I installed it, and of course, no $40 Capital One credit. I did have a $15 reward listed, but it only applied to a gift card purchase, and the only retailer I had any interest in has a minimum gift card purchase of $25. I'm not shocked that the gift card credit was a lie, but since the offer came after a purchase on a legit website, it makes it more fraudulent.
