This really works: after installing this a few months back I spend a fraction of the time I used to spend on YouTube. The problem isn’t YouTube so much as the never-ending feed of recommended vids, which I found we usually things I had already seen, clickbait, or generally just mediocre content. All the content is still there with this extension, but having to manually search it out takes away the likelihood of bingong.
