Windows 10 just installed an upgrade. My yahoo email said that there was a problem and that I should down load "Firefox". I did. Firefox says that my "connection is not Secure" SEC_ERROR_UNKNOWN_ISSUER . I have looked at your help screens. They might as well be written in a foreign language. I do not have any idea what to do next. Can you help?
