No. Apple doesn’t let plugins hook in so much because the plug-in ends up seeing a ton of data about what the user browses, and they can slow the browser down if badly written. Apple lets plugins provide lists of elements/css/IPs/etc to block. Safari processes them and is able to block stuff based on that extremely fast and power efficiently. There is flexibility lost. Plug-ins can’t see which rules are/aren’t hitting. You can’t filter based on the content of a request. So there are ad blockers, and they work well. But uBlock, as it works elsewhere (I know it’s considered the best), isn’t possible due to the trade offs Apple chose.
