I've used this on chrome and firefox for as long as i can remember. I trust it with life. It warns for unsafe websites (A pain for people like me) however you always have the option to go to it. Pretty much nukes every ad in existence and it's very rare for any ads to get through (I'd say 5-10 ads per year at max) the only better "Ad blocker" out there than this is setting up pi-hole in your home network. Don't get ABP they were paid off years ago when ads started seeping through. If you wanna block ads. This one will do it.
