I experienced same thing today on Mozilla browser. The way around it is to reset the master password. This though would delete all passwords and certificate handled by password manager.
To reset the master password, on your browser use; Edit> Prefernces>Privacy & Security>Master Passwords>Reset Passwords.
You can then change to your desire password. After 2 years, do I still get a cone?
