The MacOS Safari issue not related to the new usercp I'm working on.

It is a Mac issue giving me warning messages when I close Safari and I want some code or preference or even a hack to insure Safari will always quit without any popup warning.

I'm using Mojave on three out of four of my Macs; and High Sierra on the other (because it is too old to run Mojave).

If I have time, I'll see if I have the same issue with High Sierra. Maybe it's a feature removed or missing from Mojave.

Cheers.
