thanks for reply. Here are first some little code of which did not work, that means it crashes:

functionLoadFirefox() {
SECStatus rv = NSS_InitReadWrite(PATH_TO_FF_DB);
... if success load Certificates with PK11_ListCerts(PK11CertListAll, NULL);
NSS_Shutdown();
}

functionLoadThunderbird() {
SECStatus rv = NSS_InitReadWrite(PATH_TO_TB_DB);
... if success load Certificates with PK11_ListCerts(PK11CertListAll, NULL);
NSS_Shutdown();
}

So these are my two functions in which i opened and clos the databases and retrieve the certificates.

--> 2) To open additional databases you want to use SECMOD_OpenUserDB
So this means. First i have to call NSS_Init with let's say firefox database ad the i have to call SECMOD_OpenUserDB with the thudnerbirddatabse, right? Or must i load both with the SECMOD_OpenUserDB?

--> Once the database is opened any of the NSS find functions will find all the certs in both databases
But i have to know from which databse the certificates are coming from. So i need to know that let's say Certificate ABC ist stored inside Firefox Databse and Certificate 123 is stored in Thunerbird Database. How can i do that? or is this not possible?
