Abstract

A browser extension acts as a cross-domain persistent cookie opt-out by providing opt-out cookies. This allows users to opt-out of interest-based advertising by simply downloading one extension, essentially acting as a mechanism that prevents ad companies from personalizing ads on a per browser basis. Furthermore, opt-out cookies persist across otherwise destructive actions, such as deleting stored cookies.
