FirePassword is a free console tool that can quickly retrieve login passwords saved by Firefox.

One of the key features of FirePassword is its ability to instantly decrypt and recover encrypted passwords from the "Firefox Sign-on Secret Store." It supports all versions of Firefox, as well as Mozilla-based SeaMonkey browser. Additionally, users can specify Firefox profile locations from any remote system to recover passwords.
Even when passwords are protected with a master password, FirePassword can recover them. It automatically detects the presence of a master password and prompts the user to enter it. Another useful feature of FirePassword is its ability to automatically discover Firefox profile locations based on the installed version of the browser.
Upon successful recovery, FirePassword displays the corresponding website address, username and password. An integrated installer is also included for local installation and uninstallation.
FirePassword is compatible with a wide range of platforms, from Windows XP to Windows 10. Those who require more advanced features are encouraged to download the new all-in-one Browser Password Recovery Pro 2018 Edition.
