Since I started using this browser I am getting ads for crypto currency trading. They are grey boxes at the bottom right of my screen. These have zero interest to me. How do I stop seeing them.
Seems like Brave Ads – opt-in (OFF by default), private, and users get 70% of the revenue share.
You may accidentally enable it. You can disable it by going to brave://rewards > and flip the switch for Ads section.
