Mozilla Included CA Certificate List
The Mozilla CA Certificate Program's list of included root certificates is stored in a file called certdata.txt in the Mozilla source code management system.
If you are choosing a CA for your website, we have a list of all CAs that Firefox trusts for SSL/TLS, together with contact information and geographical focus for each CA.
If you are embedding our root store, you need to know that we have imposed some restrictions that on certain CAs or certificates which are not encoded in certdata.txt. These are documented on a best-efforts basis.
