Tried to get into yahoo mail. Get the following error message when trying to access password:

SAML 2/0 authentication failed. followed by a long e-mail address followed by; Error details FBTSML.21.5E The name identifier policy in the authentication request could not be met by this identity provider.

What gives?

You should contact yahoo email support about this since this isn't a firefox end user help support to fix another email provider login issue. Otherwise sounds like there is a certificate issue and that would be something yahoo needs to fix.
