uBlock Origin is an ad-block, web security, and privacy tool, one that I have recommended for a long time. I was dismayed to see this article today. I encourage you to read that, but here's the first line:
Very quick tl;dr: uBO will no longer with Safari, use Firefox or a new "content blocker" app (see below for good replacements).
If you read the article you'll notice that Chrome is also essentially disabling support for uBlock Origin. It's doing so for reasons legitimate to its business interests, but it's also a move that is tightening its grip on control of the user experience for Google properties. Google first, users second.
Use Firefox. Use it now, and support them now. Put your own interests first, just like Google does.
