Firefox Password Manager review

Firefox's built-in password manager is a sensible free choice for households that already use Firefox. Mozilla says Firefox stores your usernames and passwords, fills them in automatically when you return to a site and lets you manage stored logins in the browser, and with a free Mozilla account you can sync passwords across all your devices. When you sign up for a new account, Firefox can create a strong, unique password so a breach at one site does not expose others. It also alerts you if a saved password has been exposed in a data breach. Moving in is easy: an import wizard brings over usernames and passwords stored in Chrome, Edge, Safari and other browsers. The limits are the same as any browser manager. It lives inside Firefox, so logins in other browsers or many mobile apps are outside its reach, and it has no family sharing features. For one person or a Firefox-only home it is enough; for a mixed family a standalone vault is better.
