Firefox/Thunderbird/PW manager

Regarding passwords for email accounts in Thunderbird, is password manager part of Firefox, Thunderbird or Windows and how do I remove or change a password?

In FF it’s Edit - Preferences - Privacy - View Saved Passwords.

In TB it’s Edit - Options - Advanced - Saved passwords - View Saved Passwords.

No, in FF it’s Tools, Options, Privacy…


It’s exactly where I said it was, in my installation anyway …
