I do not have any problem connecting to these websites from IE. What is going on with firefox?

YAHOO - "This Connection is Untrusted - You have asked Firefox to connect securely to www.yahoo.com, but we can't confirm that your connection is secure.

hello Sasco9000, first please make sure that the date, time & timezone are set correctly on your system. if this doesn't solve the issue (or it is already set properly), a possible solution depends on different factors:

  • what security software are you using?
  • what is the error code shown under technical details on the error page?

in case the error code equals sec_error_unknown_issuer, please attempt to add an exception on the bottom of the error page - don't add it for real, but inspect the certificate (see the screenshot attached for instructions):

  • which issuer information does the certificate contain?

please report back with this information. thank you!
