why is 1Password Safari extension not working?

I'm having the exact same problem that started after I was forced into a 7.9.6 upgrade (and still holding on to a stand alone license).

Silver lining for me was that I checked out Apple KeyChain since I'm totally in MacOS, iOS environment and have been pleasantly surprised so far at how easy it was to import my 1Password vault and how well it works -- though it's only been a day. Something to look into if you don't have cross platform needs.
