Hi. I got "your connection is not secure" error only when I try to download new firefox update. I tried with other browsers(Edge, Chrome, etc) and got same error. Anyone has solution for this?

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

Boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems.
