SponsorBlock for Safari

YouTube is great, but you know the part that wears you down: sponsor segments, long intros, like-and-subscribe routines, and other padding that turns a ten-minute video into a fifteen-minute commitment.
SponsorBlock for Safari is designed to skip those segments when you watch YouTube in Safari. Of course, you still have one downside: this is for YouTube in the browser, not inside the YouTube app. If you live in the app, this won’t change your life. But if you’re willing to watch your favorite videos in Safari, it can save a shocking amount of time.
It’s also nice to know that Safari extensions aren’t just about blocking ads. Some of them are about making the web feel less wasteful.
