DuckDuckGo – Pop-up ads

I have used both DuckDuckGo and Microsoft for my web browsing. With Microsoft, I can add extensions to prevent pop-up sites and prevent ads. With DuckDuckGo, I look for that option and have not found it. I get annoying pop-ups when trying to stream on a movie/entertainment site. I also looked for a way to block those sites and didn't find anything either.

Another issue I have with DuckDuckGo is there is no customization for fonts and text sizes.
