Certificate issuer issue (linkedin.com and wiki.mozilla.org known so far)

I don't understand why, but I got invalid certificate error (Error code: sec_error_unknown_issuer) when I visit linkedin.com or https://wiki.mozilla.org/CA:PendingCAs.

It seems DigiCert SHA2 Secure Server CA and its owner is installed in my Firefox 40.0.3.

Does anybody have any ideas what could be the problem?

Thanks in advance!

hi, one thing you could try is to rename/delete the cert8.db file in your profile folder like described at "This Connection is Untrusted" error message appears - What to do
