"
AV software perhaps?"
All security apps are configured with exceptions or Allow/Trusted for Pale Moon. Except for outbound rules in the packet firewall - ports 80 and 443 only, all others "ask" - gotta keep an eye on that 843, 1935 and proxy (8080 etc) stuff and block the dangerous ephemerals to those weird IPs/domains not yet on the blacklists.

You should grab the portable package and extract the fresh copy, then copy over your profile from the one you are using now."
That's exactly what I do when I "upgrade" my portables, Pale Moon and otherwise.
Specifically, I rename my Pale Moon folder from
c:\portables\palemoon64
to
c:\portables\palemoon64-PREV (for previous)
and create a new palemoon64 folder and extract to it.
I then run it to make sure the "install" went OK then copy over the "PREV" Default folder. I wait a few days before deleting the palemoon64-PREV folder.
Anyhow, thanks for the input. I've been using 20.2.1 for 4-6 hours a day since July 8 without issue and I'm keeping 20.2 as is on the non-Aero Laptop. No lost sleep here.
We'll see what happens when the next major Pale Moon arrives. October? v24?? Oh, the suspense!
Worst comes to worst, I'll just have to build a new profile. I think the one I'm using now goes back to v15...
Cheers.
