Cashback Browser Extensions
An extension does the part everyone forgets. It wakes up on the retailer's site, tries the codes it knows about, and switches cashback on without a detour through a portal. This is for shoppers who want the saving to happen automatically instead of remembering another login. It lists extension-first products, where the extension is the whole business rather than a companion to a cashback site. Portals that ship their own extension are listed once, under the account that holds the balance. We rank on how many US retailers actually trigger the button, whether the codes it finds still work, and how clean it is about your browsing data.
