It is a pity that Apple decides to castrate Safari's API in such a way that uBlock Origin won't function.

It is the best AdBlock out there in my opinion. Works especially well for certain dirty pages with nasty ads.

Apple introduced content blocking in Safari in iOS 9 with privacy in mind. Essentially, content blockers started off as filter lists that Safari would use. Even with the more recent support for WebExtensions, this wouldn’t allow uBlock Origin because uBO gets to see every network request made, intercept it, match the requests with the blocking rules and prevent or allow them. Granted that uBO is trustworthy and has never siphoned off browsing behavior to other systems. But that risk exists with almost every extension of this kind on other browsers.

I use Firefox with uBO, and am not supportive of Apple’s position on not allowing uBO. But I see the value in controlling what information browser extensions can see, capture and possibly exfiltrate.
