I get "Connection is not secure" on every website. Error code is SEC_ERROR_UNKNOWN_ISSUER. Certificate issuer on every website is "ffeb984503f19da0 2". Problem is only on Mozilla Firefox. I've tried to reinstall and refresh Mozilla without success. I don't have avast, kaspersky or others which have been causing same kind of problems. I've run three programs full virus/malware scans without any found threats. I'm pretty sure that that certificate issuer is the problem but I have no idea how to fix it or what causes it. Help please. Thank you!

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