startssl client authentication certificate

[thufir]

When I filled out the forms at startssl.com firefox downloaded the 
following file:

thufir at dur:~/Downloads$ 
thufir at dur:~/Downloads$ head getcrt.ssl_certID\=2032879 -n 3
-----BEGIN CERTIFICATE-----
MIIMtAYJKoZIhvcNAQcCoIIMpTCCDKECAQExADALBgkqhkiG9w0BBwGgggyHMIIG
SzCCBTOgAwIBAgIDCkKTMA0GCSqGSIb3DQEBBQUAMIGMMQswCQYDVQQGEwJJTDEW
thufir at dur:~/Downloads$ 

However, when I look in firefox, there are multiple certificates from 
StartCom, but I'm not sure which one is the certificate I'm after.

Is this the client authentication certificate?
