@meowmeowwoofwoof If you on Samsung, check if the app store have Samsung Internet app ( purple background, white circle, purple ring around it.) It has a best free ad blocker. They are really good at blocking ad at worst site as well.
@Seirra have you tried use Brave browser's built-in, aggressive adblocking capabilities? Zero ads in mobile or desktop. Sometimes, the popups get creative and will redirect you. Just hit the back button. You can customize what gets blocked in the Shields settings. After a few days, it goes back to 100% ad free.
