Any time you choose to have Mozilla Firefox save your passwords to log into a page the next time you visit it, they're stored on your computer. All of these passwords are also visible to anyone who goes into the security options of Firefox. To help secure your password information from anyone else using Firefox or from anyone that could steal your computer, follow the steps below to set up a Master Password.

  1. Open Firefox.
  2. Click Tools and then Options.
  3. In the Options, click the Security icon.
  4. Check the Use a master password option.
  5. Enter your master password and click OK.

To view saved passwords, click the Saved Passwords button and then click Show Passwords. If the master password has been set up properly, you'll be prompted for a password before being able to view all saved passwords.


You should never choose the option to save a password when logging into someone else's computer due to how the passwords are saved and easily viewed. Also, be sure to follow all the steps for keeping safe online.
