icloud passwords for firefox on windows

Hi Apple Community- I am trying to standardize on one single password manager and I like the security of my iPhone and the Apple platform. Unfortunately, I run Windows 11 on my "work" computer at home (MacBook Pro Laptop for "personal" use) and, while iCloud Passwords works with Microsoft Edge and Google Chrome ... I am not comfortable with these companies' privacy and data collection practices. I would prefer to continue using Mozilla Firefox. There doesn't seem to be a supported plugin to enable Apple iCloud Passwords for Firefox though!

I found this unofficial one that might do the trick but so far only Firefox on Mac is supported... and I would really prefer a version from Apple (even though Aurélien seems like a trustworthy person).

Any ideas?
