Have been trying this out. But one thing that is a bit concerning is that, since I'm only trying it out, haven't yet set Little Snitch to allow all port 80/port 443 connections from WF, as I have with my 52esr or FF 59, I'm seeing any number of outgoing connections, almost all of which are necessary.
Wondering though, how this particular prompt got established, seemingly out of the blue--and what would happen if I had allowed it, as might already be occurring with my other FF browsers. Since I can't possibly attend to all these needed (and not some not so needed) outgoing connections for various sites, will at some point have to allow all from WF for ports 80/443, just as I have elsewhere. If allowed, where would this kind of garbage get stopped, at uMatrix, NoScript? Used to have Request Policy, now defunct, but using that was a big PITA, so even before its demise had stopped using it. What do I have to worry about if this kind of garbage is allowed to connect?
