I was using ublock origin lite but now I've converted to wblock. Absolutely amazing, works inside webviews (e.g. netnewswire). v3 just released. https://github.com/0xCUB3/wBlock

“It's not the best ad blocker, I've found wBlock - https://github.com/0xCUB3/wBlock - is more effective, anecdotally and via adblock.turtlecute.org”

This is different because Firefox Focus, a separate app, only blocks ads while using Firefox Focus. Firefox Focus can also be set as a Safari Content Blocker which allows Safari to benefit from Firefox Focus's ad blocking. (It's not the best ad blocker, I've found wBlock - https://github.com/0xCUB3/wBlock - is more effective, anecdotally and via adblock.turtlecute.org) Regular Firefox (non-Focus, the app from the article) can not benefit from Safari Content Blockers, and therefore does not benefit from Firefox Focus's ad blocking.
“wBlock by an MIT student is open source and seems (just!) about as trustworthy as uBlock”

wBlock by an MIT student is open source and seems (just!) about as trustworthy as uBlock, though of course without the track record. Light & fast, especially to update. “wBlock runs entirely within Safari's content blocking API. There's no data collection, no tracking, and no system-level extensions that can monitor your browsing.“ https://apps.apple.com/us/app/wblock/id6746388723 / GH: https://github.com/0xCUB3/wBlock On AdGuard: can act as your PiHole and allow you to see network requests when run in non-native mode.
