How to Use Firefox’s Master Password to Protect Stored Logins and Passwords?

With many web browsers available in the market, Firefox is the only one that is developed by a nonprofit organization, Mozilla. The browser is well-known for its customizability and safety. It does everything in its possession to keep user’s data safe by providing a suite of security features. For example, Firefox has a built-in password manager which helps you save your time and bring you lots of conveniences. The password manager makes you no longer need to remember long alphanumeric sequences for every single website that you register on, because Firefox saves your passwords and auto-fills them whenever a specific website requires you to enter your passwords. And Firefox’s password manager is one of the safest browsers in the world, thanks to its master password feature. Any passwords you save on Firefox will be encrypted with this master password which you have to enter before using the password manager. In this way, no one can see your passwords even if they access your computer, because without that master password, Firefox refuses to give you access to those saved logins. But how do you set up Firefox’s master password and use it to protect your stored logins and passwords when credentials are saved by the browser? It’s actually quite simple. Let me show you.

What Does Firefox’s Master Password Do?

Before we get started, let’s figure out what Firefox’s master password is and how it works. Mozilla Firefox allows you to save the login details, such as username and password for the websites that you visit on your computer. However, in some cases, you have to share your computer with others, or step away from your computer for a moment and of course you would not want anyone to see your stored personal information, then Firefox’s Master Password helps you protect your locally stored usernames, passwords and certificates from being viewed. With this feature enabled, no one will be able to view your passwords, unless they have your Master Password. It is an extra security mechanism and can protect your sensitive data.

How Do You Set Firefox’s Master Password?

1. Download & Install Mozilla Firefox browser on your computer.

2. Open Firefox. Click the Menu button.

3. Click Options.

4. In the Preferences window, click Privacy & Security. Click the checkbox for Use a master password.

5. Set up your master password. Once you finish this step, the “Password Required” dialog box will pop up each time you try to access your passwords stored in the Firefox password manager. This gives an impression that Firefox gives you all the tools necessary to protect your personal information from anyone (besides you) seeing it.


Firefox’s master password protects your logins and passwords when they are saved on the web browser. So, you’re concerned about your security, and you don’t want to remember or type your usernames and passwords every time, this is a must-use feature for you. However, there are a number of security concerns associated with the Firefox’s Master Password and it is far from enough to ensure that nobody else could uncover sensitive data. We recommend users consider use a real password manager like Dashlane, LastPass or Sticky Passwords to protect their passwords. In fact, they are not just about protecting your data, they can make your web browsing and logging with a more convenient experience. A real password manager stores anything from login credentials to important or sensitive notes in a secure environment and it works the same way as Firefox’s own solution with many additional features. Therefore, you can have a perfect combination of convenience and security
