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.
Additional System Details
- User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.140 Safari/537.36 Edge/17.17134
There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
