Thanks, but that's not the problem. I never did run FF 60 ESR and I always start from scratch with each new version of FF Quantum.
There's just something "funny" with the way the new versions handle updates (which I do not permit automatically).
The extension I'm having problems with is uBlock Origin.
Add to that I have opted out of "Recommend extensions as you browse" and yet recommendations still pop up on the extension page (the same ones over and over). So much for honoring preferences.
