Mozilla’s CA Certificate Program governs inclusion of root [https://developer.mozilla.org/en-US/docs/Mozilla/Security/x509_Certificates certificates] in [https://developer.mozilla.org/en-US/docs/NSS 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 [[Modules/Activities#CA_Certificates|CA Certificates Module]]; the policy itself is overseen by the module owner and peers of the [[Modules/Activities#Mozilla_CA_Certificate_Policy|CA Certificate Policy Module]].
