Resetting the master password

Just experienced the "Mater Password" problem in T-b, successfully solve it by following the below direction:

If you have lost or forgotten your master password or you want to disable the feature, you can reset the master password. Resetting the master password will remove all stored password information. Upon resetting, you will lose all the stored information in the Password Manager, as this is a built-in security feature to prevent people from simply resetting your Master Password to gain access to your passwords.

• Firefox: Enter chrome://pippki/content/resetpassword.xul into the Location Bar (address bar), press the "Enter" key and click "Reset".
• Thunderbird: Choose Tools -> Error Console, paste the expression: openDialog("chrome://pippki/content/resetpassword.xul") and press the Evaluate button. That will open a dialog asking you if you want to reset your password.
• Mozilla Suite/SeaMonkey: "Edit -> Preferences -> Privacy & Security -> Master Passwords -> Reset Password".
