Mozilla's CA Certificate Program
Mozilla’s CA Certificate Program governs inclusion of root certificates in Network Security Services (NSS), a set of open source libraries designed to support cross-platform development of security-enabled client and server applications. The NSS root certificate store is not only used in Mozilla products such as the Firefox browser, but is also used by other companies in a variety of products. The program is overseen by the module owner and peers of the CA Certificates Module; the policy itself is overseen by the module owner and peers of the CA Certificate Policy Module.

The following Mozilla public forums are relevant to CA evaluation and related issues.
- Mozilla's dev-security-policy (MDSP) mailing list is used for discussions of Mozilla policies related to security in general and CAs in particular, and for wider discussions about the WebPKI. Among other things, it is the preferred forum for the public comment phase of CA evaluation. If you are a regular participant in MDSP, then please add your name to the Policy Participants page.
- Mozilla's dev-tech-crypto mailing list is used for discussions of the NSS cryptographic library used in Firefox and other Mozilla-based products, as well as the PSM module that implements higher-level security protocols for Firefox.
- For other discussions of Mozilla security issues:
- Mozilla's Security Web forum is a place to discuss information security work in the open source space, where Mozilla is empowering users to build and curate a Healthy Internet.
- Mozilla's privacy-and-security forum is a place to discuss issues and questions specific to privacy and security.
