This is one of my foremost requirements from a browser these days; how well does it block ads. As much as I like Safari it doesn’t seem to block ads as well as Brave, so Brave is my daily driver.
Safari doesn't have an adblocker, but delegates to the ones you can install from the App Store.
I totally understand that lacking a content blocker can be a deal breaker for some people. I wanted to ship my app to the App Store quickly in order to get user feedback.
