Opened Firefox & heeded admonishment to "refresh" the browser by upgrading. Now not one site will load! All are returning this:


"The owner of abc.go.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website."

Browser is useless if it won't open any websites! Things were working fine prior to upgrading to "61.0.2 (64-bit) Quantum"; I am working on a Mac, and Chrome and Safari are just fine!

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