I have been, with Safari for many years and anything has never been sneaked in or have ever suffered any problem in my machine. Of course, I am in Mojave behind the firewall Vallum and all the traffic from outside passes through a proxy and port 3128. I am no fool who discharges any unknown sources nor do I open anything that does not examine its sources. Social engineering with me does not work ;-)The most fantastically agile thing about Safari is how quickly it will acquire some sort of browser malware the split-second Apple drops support for its host OS. (It's as bad as Internet Explorer was back in the day, and always the second thing I delete off the dock after News.)
Kind regards
