- Use a master password: Firefox can protect sensitive information such as saved passwords and certificates by encrypting them using a master password. If you create a master password, each time you start Firefox, it will ask you to enter the password the first time it needs to access a certificate or stored password. You can set, change, or remove the master password by checking or unchecking this optionpreference or by clicking the button. If a master password is already set, you will need to enter it in order to change or remove the master password.
