I'm getting annoying Brave browser 'brave rewards' pop-ups. How can I shut that off? I don't care about their 'rewards', I just want the pop-ups to stop.
You did this to yourself.
Brave Rewards are opt-in by default. This means they were off and you went into the settings and enabled them.
Click the triangle to the right of the address bar, click Rewards Settings, and then turn off what you don't want.
