Firefox Password Manager is an integrated feature of the Firefox web browser that helps users securely store their website passwords. It was introduced in 2004 and has since become an integral part of the Firefox experience. However, in recent years, Firefox has been transitioning away from its own password manager in favor of third-party services like LastPass and 1Password. This means that while it's still possible to use Firefox Password Manager, it's no longer the default option for managing website passwords within the browser. Mozilla has also made some changes to how users manage their stored passwords, such as requiring re-authentication before viewing or modifying them. As a result, some users may find it difficult to access their saved credentials or use the tool as they did previously.
