Can't open Firefox with Yahoo home page. Have done so for years. Needs to be fixed.
Received error message: An error occurred during a connection to www.yahoo.com. security library: improperly formatted DER-encoded message. (Error code: sec_error_bad_der)
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem.
Been using Yahoo as my home page for years and years and all of a sudden it's a problem. I can open it easily on Safari browser even though I don't have an Apple computer. So the problem has to be with Firefox, not Yahoo. I've read all of your solutions, tried troubleshooting them, and it still doesn't work. I contacted Yahoo and they haven't responded, probably because the problem isn't on their end, but on Firefox.
Please fix or I will have to stop using Firefox as my primary browser.

Thank you for checking that.
When you get the error page for https://www.yahoo.com/ if you expand the technical details section, does it still have that same unusual code, sec_error_bad_der, or is it showing anything different after the Reset?
Does the error page have a section entitled I Understand the Risks that contains an "Add Exception" button? You can use that button to view the certificate that Firefox is rejecting and compare it with the attached screen shots of what I see for that certificate.
