I recently discovered uBlock Origin for use with Ungoogled Chromium. Looks good, and I'd like to cut back on ads & trackers in Safari also. However uBO doesn't work with Safari after v.11, while I'm using Safari 12.1.2 (MacBook Pro 2014), the last available for macOS 10.12 Sierra. The uBO folks suggest a couple good (they say) blocker extensions for post-11 Safari, but they require macOS 10.13 High Sierra, while I want to stay with Sierra. A lot of options show in the App Store, but I don't know where to start. Can anybody recommend a blocker extension similar to uBlock Origin that works with Safari 12 in macOS 10.12 Sierra?
