can't work on windows11

I install it, it prompts me to download icloud for windows... which I already have. I've uninstalled, reinstalled, changed settings, and nothing works. This is no good at all - it doesn't even deserve the 1-star rating.

Maddeningly bad, constantly stops working. In fact, I've never gotten it to work for more than a month without it losing connection. Then I'll have to spend an hour trying to reconnect over and over, pulling out my hair while all of the Apple instructions don't work at all. Then, randomly, it will reconnect and I will get it to sync for a few days.
Lame.

I loved this extension. Up until a few weeks ago, the extension and Windows app used to work just fine with Firefox and Google Chrome. Now it will only sync with Chrome and I can't, for the life of me, get the Windows app to connect to Firefox.
