I am unable to access my gmail account or my Linkedin account with FireFox. I get a certificate error SEC_ERROR_UNKNOWN_ISSUER yet this is a valid site and account. When Firefox gives the error it will not allow me to add a certificate exception, so I cannot use Firefox for these sites and probably others.

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
