Intermediate CA Preloading is reducing errors today in Firefox for desktop users, and we’ll be working to roll it out to our mobile users in the future. While there are other factors that affect the relative prevalence of this error, this data supports the conclusion that Intermediate CA Preloading is achieving the goal of avoiding these connection errors for Firefox users. Our collected telemetry confirms that enabling Intermediate CA Preloading in Firefox 68 has led to a decrease of unknown issuers errors in the TLS Handshake. Trust is still derived from the standard Web PKI algorithms. The list can be examined directly using your favorite JSON tooling at this URL: įor details on processing the records, see the Kinto Attachment plugin for Kinto, used by Firefox Remote Settings.Ĭertificates provided via Intermediate CA Preloading are added to a local cache and are not imbued with trust. The list changes slowly, so once a copy of Firefox has completed the initial downloads, it’s easy to keep it up-to-date. When Firefox receives the list for the first time (or later receives updates to the list), it enumerates the entries in batches and downloads the corresponding intermediate CA certificates in the background.

Currently the list contains over two thousand entries. Given this information, we periodically synthesize a list of these intermediate CA certificates and place them into Remote Settings. Consequently, all of the relevant intermediate CA certificates are available via the CCADB reporting mechanisms. As a result of Mozilla’s leadership in the CA community, each CA in Mozilla’s Root Store Policy is required to disclose these intermediate CA certificates to the multi-browser Common CA Database (CCADB). This way, Firefox users avoid seeing an error page for one of the most common server configuration problems: not specifying proper intermediate CA certificates.įor Intermediate CA Preloading to work, we need to be able to enumerate every intermediate CA certificate that is part of the trusted Web PKI. In essence, Firefox pre-downloads all trusted Web Public Key Infrastructure (PKI) intermediate CA certificates into Firefox via Mozilla’s Remote Settings infrastructure. This technique reduces connection errors that users encounter when web servers forget to properly configure their TLS security.

We’ve been improving connection errors overall for some time, and a new feature called Intermediate Certificate Authority (CA) Preloading is our latest innovation. Throughout 2020, Firefox users have been seeing fewer secure connection errors while browsing the Web.
