AI Summary

This case concerns a request to remove the CNNIC CA root certificate from NSS after a third party filed a bug asking Mozilla to remove it. The thread quickly filled with public comments alleging CNNIC was untrustworthy and raising concerns about government influence, possible policy violations, and the security impact of trusting the root. Mozilla staff responded that Bugzilla was not the right venue for advocacy, asked for concrete evidence of policy violations, and pointed users to the certificate manager for disabling trust locally. Kathleen Wilson later summarized that Mozilla had received reports of possible Mozilla CA Certificate Policy violations by CNNIC, said Mozilla had previously reviewed and accepted the root, and asked for substantiated evidence and professional discussion. The bug was ultimately resolved as INCOMPLETE, and the thread does not record a removal of CNNIC from the Mozilla root store.
