Vpn with ad blocking built in

The only other extension I’ve started using recently, when the quantity/frequency of YouTube ads on Safari became unbearable, is 1Blocker. It includes a specific filter for blocking YouTube ads, and you can use one active filter for free without subscription.

Unfortunately, because real alternative browsers are only supported in the EU (and even then with big asterisks), you won't see a normal browser engine powerful content blocking any time soon. The content filters you can download from the app store help, but they're not as powerful as uBO and friends.
I think the extension support is explicitly disallowed by Apple so shhh don’t tell anyone teehee!
