Cookie management is now handled by firefox natively. In your FF browser bar, go to about:preferences#privacy
and choose Strict. Then you can remove AutoCookie Delete extension. If you want to know more, find the the Firefox blog posts about Total Cookie Protection. There are multiple posts on the topic.
Edit: If you want to be super intense, you can also check the box, “Delete cookies and site data when Firefox is closed” although that isn’t strictly necessary if your ETP is set to strict.

They recently implemented some in app analytics. But it’s opt-in. The feature is turned off by default. 1Password still pretty great, especially if you are using it with your family.
