1Blocker is a beautiful and powerful content blocker for Safari. 1Blocker provides best-in-class ad blocking, including blocking ads on YouTube.com, which is notoriously difficult. But we offer much more than just ad blocking. Our default filters include various categories, such as blocking of annoyances, like cookie notices, blocking of trackers, and adult sites.
