I have been needing a pop-up blocker for years. The websites I am referring to are the anime websites where I stream anime. uBlock Origin blocks all my pop-ups and I'm super happy! I also have Kaspersky Internet Protection, which blocks the ads on the pages I'm visiting, but doesn't block pop-ups when I click on links/hosts/website/anime/episodes (forgive me if I identify incorrect names). I also have block pop-ups defaulted on Mozilla, but that doesn't block my pop-ups on the anime websites.

I just downloaded it today, but I see the big difference and I'm super happy that I don't have to keep closing down multiple (and sometimes inappropriate) pop-up windows.
