It turns-out, I was running TWO different firewalls, which I have since learned, I WASN’T supposed to be doing .
So, I turned-off the Apple Firewall, and just left Little Snitch, running .
Also, my copy of Firefox, KEEPS getting corrupted, so I periodically re-load, THAT !
I can’t seem to re-download Safari, without re-downloading the ENTIRE macOS !
