I’ve noticed a couple people coming to this site searching for help on resetting their master password in Mozilla Firefox, so I found help on this and am posting it here in case you happen to be one of those people. :)

Master password - MozillaZine Knowledge Base

If you have lost or forgotten your Master Password or you want to disable the feature, reset your master password. Note that, upon resetting, you will lose all the stored information in the Passwords Manager as this is a built-in security feature to prevent people otherwise resetting your master password and gaining access to your passwords.
  • For Firefox: go to “chrome://pippki/content/pref-masterpass.xul” (see Chrome URLs) and click on “Reset Password”.
  • For Thunderbird: “Tools -> Options (Edit -> Preferences on Linux) -> Advanced -> Saved Passwords -> Master Password -> Reset Password”.
  • For Mozilla Suite: “Edit -> Preferences -> Privacy & Security -> Master Passwords -> Reset Password”.
