I was using Safari up until they have yanked support for extensions. The web is unusable, outright hostile place without a proper script blocker. I can tolerate a lot of things, but browsing the web without uBlockOrigin isn't one of them.
Advertisers are already figuring out how to get around that. CNAME cloacking, proxying with same domain, etc.
This idea of removing usability in the name of safety has gone way, way too far. It was crap when Mozilla did it, it's crap when Apple does it.
1. Extensions in the app store are not easily searchable. They aren't indexed/sorted on the store properly, and many only show up on Google.
2. Many of the good extensions are no longer available, e.g., UBO and KeePass, Vimium (there is a Vim extension, but it's a poor replacement so far).
3. The store promotes junkware and throwaway extensions.

In July 2018, uBlock.org was acquired by AdBlock,[19] and began allowing "Acceptable Ads",[20] a program run by Adblock Plus that allows some ads which are deemed "acceptable", and the publisher pays Adblock Plus.[21]

uBlock was the original tool but was handed over to another maintainer some time ago. The original developer of uBlock, being unhappy with the direction of the tool, forked the repo and made uBlock Origin which he maintains and is often considered the better product by people here

It's basically racketeering.
If you're keen on using chromium with manifest v2 add-ons, Vivaldi and Microsoft edge are both options to keep in mind.
Edge hasn't been released yet.
Vivaldi UI is a buggy and slow mess (I invite you to try it yourself)
(They are both based on Chromium....)
