• Most of my back and forth on this topic has been with joemike, who's running High Sierra beta, while you (I believe) and I are running Sierra.
  • While I've found any number of Google references to "Enable content blockers" in Safari 11 in High Sierra, I haven't found a single one dealing with Sierra.
  • I'm therefore wondering if, as unlikely as it sounds, we're dealing with a feature that is built into Sierra but hasn't been turned on yet?
