Error code: SEC_ERROR_INADEQUATE_KEY_USAGE
Hello,
I would like to ask you about error code that I got after last firefox upgrade to 78.3.1esr (64-bit). Everytime I go to certain websites I get this error message:
Error code: SEC_ERROR_INADEQUATE_KEY_USAGE
Please, can someone advise about this? I do not see any known bug with this code. I did not have this problem before this upgrade.
Thank you, Martin

From my research, it looks like a certificate issue. https://www.bing.com/search?q=SEC_ERROR_INADEQUATE_KEY_USAGE
There is security software like Avast, Kaspersky,
BitDefender and ESET that intercept secure
connection certificates and send their own.
