Really great extension for Safari on the Mac. Even though I’m not overly bothered by ads; I do want to block tracking script, social & share widgets. 1Blocker does it nicely! Another great feature, it syncs with the iOS app as well! Also, performs better (I think?) thanGhostery.
The developer is also engaging their users. Always a good sign, knowing the developer behind the product actually cares about feedback and improving their product.
