This connection is untrusted error reportwhen trying to check e-mail

Posted

Every time I try to get my Yahoo or Google e-mail, I get the following message "You have asked Firefox to connect securely to us-mg5.mail.yahoo.com, but we can't confirm that your connection is secure. Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified."

I have tried uninstalling and reinstalling Firefox, and tried deleting cert8.db. file and nothing has worked.

How do I fix firefox so that it will work with two of the most popular e-mail addresses?

hello bgreenberg, maybe your antivirus software is interfering here. does it make a difference when you disable the scanning of encrypted connections/https within the kaspersky network settings?
