The Safari Ad-Block extension is installed in Safari and effects ONLY Safari. The Ad-Block app is installed in the applications folder, resides in the menu bar, and effects all internet browsers and apps on the system.
Thanks for the clarification, but I'm totally confused about which piece of software this thread deals with.
A search for "future mind ad block", the subject of Jon's linked article, comes up with an iOS app, but not the macOS app you've implied, and a search for "ad block" (various spellings) doesn't seem to come up with it either, so would you please post a link to it?
