Hi arejfour, Do you have a Primary Password set in Firefox -

Use a Primary Password to protect stored logins and passwords https://support.mozilla.org/en-US/kb/use-primary-password-protect-stored-logins

Thank you for your reply, but, this doesn't solve my problem. I don't use a primary password and never have. What I want to know is why I can see my passwords without logging in using the system password?

Your Windows User Account Password does not manage your Firefox Logins & Passwords (Lockwise).

If you were to add a Password Manager Extension, like LastPass, you would need to set a password there to protect those logins & passwords.

In Firefox, set a Primary Password to protect your stored logins and passwords

Note that using Biometrics like Windows Hello/PIN instead of the Primary Password to protect the logins is less secure as it doesn't encrypt the logins stored in logins.json like the Primary Password does and having access to logins.json and key4.db and place them in a Firefox profile is sufficient to inspect the logins. Using Biometrics is merely to make it harder to access/view passwords in Password Manager, but Firefox will still be able to fill a login on a webpage without asking. Note that this is also the case if you unlock the passwords via the Primary Password during a session.

Firefox does support this Biometrics feature, but it hasn't been enabled.
