Websites blocked; security connection failed message is SEC_ERROR_BAD_SIGNATURE, therefore need a quick solution or discontinue using Firefox
More and more of my favorite websites are blocked, so increasingly having to use MS Edge as a default browser. It is very frustrating so a solution would be most welcome. I can't even use this Mozilla help website so have had to use MS Edge to convey this message.
There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
