Have you lost your master password?
If you want to add another layer of protection to your Firefox browser, you can turn on the master password option. In short, this will allow you to secure your login information – especially if your PC is used by more than one person, so they can’t snoop through Firefox’s options and find your passwords.
Now if you find yourself not remembering your master password, there is an easy way to reset it. There is a down side though, because resetting your master password will remove all of your saved user names and passwords. To start the process, copy and paste this location into your Firefox address bar:
This is your “Reset Master Password” page. For one more time, it warns you:
If you reset your master password, all your stored web and e-mail password, form data, personal certificates, and private keys will be forgotten. Are you sure you want to reset your master password?
Then you will be given the option to “Reset” or “Cancel”. Hit the button labled “Reset” and your master password should be reset.
