    This app is really effective. Since I installed it, the advertising has disappeared. Nice

    i was always thinking this kind of extension and program is scam or not working or like they are hacking or getting my data , but after truly honest research realized no they do work and they save you time while doing something important suddenly an ad pop up is annoying so thats the reason i like ad block and if i had money would donate them too
