Master password is another layer of security protection to Firefox browser. It restricts unauthorized users to view credential information (saved logins) on your Firefox internet browser such as usernames, passwords, cookies, etc that you use to access online accounts.

Recommended for you: Use Inspect Element As a Password Cracker Tool.

Firefox saves these credentials on browser’s setting. Firefox browser offers to remember password in a pop up while login to any site and if you use remember login feature, then we recommend you to use master password to protect such information from any other person who use your computer.

Note: Resetting Firefox master password will remove all your saved usernames and passwords. So it’s my advice to take a backup of your Firefox Profile – this is a default profile folder where Firefox stores your installed extensions, bookmarks, browsing history, login passwords and other user data.

To view Firefox profile folder. Press Win+R (to launch RUN) => Copy-paste the following shortcut URL in the RUN and hit enter.
