A definite must have extension along with uBlock Origin & Decentraleyes. I started using this recently when I was redirected by Putlockertv.to to a pop-up/under that managed to put a virus on my computer that everything I have completely missed until I used ESET's online scanner to get rid of it. This absolutely is the only thing I've come across that really works in deflecting this increasingly annoying bug bear. I really hope the developer continues to maintain this, wouldn't surf without it and a big thank you... 5/5
