The master password is another layer of security protection for 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: 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 the master password to protect such information from any other person who uses your computer.

How to Reset Firefox Master Password

Using a Master Password, you can protect stored logins and passwords that you use to access online services – banking, emails, social media, etc. If you’ve set a password, you’ll be prompt to enter it once Firefox needs to access your stored passwords.

But anyhow if you need to remove this password completely from the browser (in-case you lost it), then follow steps to easily reset the saved password in Firefox:

  • Launch Mozilla Firefox web browser.
  • Copy below URL and paste it into the Firefox address bar and hit enter.
  • As soon as you hit enter after entering the above URL, the Reset Master Password page will appear.

  • Now read all the information carefully provided on the password manager page and if you agree click the Reset button to reset Mozilla Firefox core password.

Firefox main password will be removed. You can now choose any other password to protect your saved logins.

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.
