Apple’s method of ad blocking - having a JSON file that gives the browser engine rules is relatively browser intensive - at least in regards to what mobile processors could do during the iOS 8 era. Apple didn’t even support it on 32 bit phones that did run iOS 8.
Apple could have only shipped it two years sooner for iOS. iOS 8 was the second version of iOS that supported 64 bit processor.
Apple didn’t just come up with the idea of ad blocking because of Firefox. Apple couldn’t implement the form of ad blocking that Safari uses on its mobile processors and still keep Safari performant before the iOS 8/iPhone 6 era. You could tell the performance difference on the iPhone 5s (the first 64 bit iPhone). They didn’t even support it on 32 bit phones.
