When you obtain a KCA certificate with the Kerberized Certificate Authority Provider for Network Identity Manager, it places the certificate in the Windows "My" Certificate Store, which is the default location for storing personal certificates. Applications that make use of the Windows certificate store will be able to immediately use the certificate. However, the Mozilla family of products don't use the Windows certificate store by default.
The KCA provider is bundled with a PKCS #11 module for Mozilla products that exposes the Windows certificate store. This allows Mozilla products to use these certificates transparently. At the current time, this module needs to be manually added to each Mozilla application that you would like to use with KCA certificates. This page provides information for installing the module for various Mozilla products.
Note: The PKCS #11 module exposes all the certificates in the Windows "My" certificate store, not just the KCA certificates.
