Brave Web Browser is a fast, free, secure web browser with a built-in ad blocker*, tracking and security protection, and optimized data and battery experience. *What is Brave Ad Replacement? Brave’s goal is to speed up the web, stop bad ads and pay publishers. One of the ways we plan to accomplish this is with ad replacements. We will also invite users to fund their wallets and to use those funds to pay the publishers of their favorite websites.
