It's surprising how much putting the following in one's hosts(5) file helps: 0.0.0.0 adservice.google.com ::1 adservice.google.com

I got none of these things on my personal iMac. It took a day or two for me to realize that it wasn't about (e.g.) the different version of macOS or Safari that I was running. Once I updated the work machine's hosts(5) file things it was a night-and-day difference. I cannot believe that people tolerate surfing the web without any ad filtering / blocking.
