Earlier quoted context omitted.
You're not going to find the same AdBlockers that Chrome/FF have, but you will find AdBlockers that _work_. I agree that ads make the web unusable, but I've been content with the various blockers I've tried on Safari, and there's more every day. I use ABP, but 1Blocker and Wipr look good, and Safari's got the first 30% of privacy/adblocking taken care of with their various privacy and reader features.
1Blocker is a rip off. Wipr doesn't work properly. ABP lets a lot of ads through. There is nothing that approaches uBlock at all.
How does it not work properly? Been using it and am pretty satisfied so far.
