If using the chrome url (chrome://pippki/content/resetpassword.xul) doesn't work then delete the key3.db and signons.sqlite files in the Firefox profile folder.

You lose all stored passwords if you use the chrome URI or delete signons.sqlite and key3.db to reset the Master Password.
You need to set a new Master Password.

That solved my password problem. I appreciate the help. Thank you very much and thank you FireFox for the best alternative to Internet Explorer. Thanks, again.

You're welcome
