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.

What do the security warning codes mean
