Things work reasonable well after deleting the old extension and reinstalling.

It's not quite as well integrated as passwords are in Safari (no password generation, that I can see at least), but it gets the job done.


A few notes:
* it doesn't display the title of the password in the dropdown when allowing you to select which one to use, only the username + the first website associated with it.

* Using Grafana, when clicking on a dropdown selector for a variable with a large number of selectable options (1,000+), the page often becomes completely unresponsive, and I'll get a banner telling me that "*iCloud Passwords" is slowing down Firefox. To speed up your browser, stop that extension." after about 10 seconds [0]. (FF 133.0.3 (aarch64), Passwords Version 1.2 (20620.1.16.11.8), Extension 3.0.6, about 400 stored Passwords)

* Apple really needs to clarify the lineage of the extension on the homepage. It's confusing looking through older comments and seeing a developer with seemingly no association to Apple responding to issues. I had to verify through news articles that they had actually acquired the extension.
