For Intermediate CA Preloading, Mozilla enumerates all of the intermediate CA certificates in the trusted Web PKI, with the relevant ones available through the multi-browser Common CA Database 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 CCADB, the browser maker explains.
According to the company, Intermediate CA Preloading in Firefox 68 has resulted in a lower number of unknown errors when a TLS handshake is performed.
"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," the company says.
While Intermediate CA Preloading is currently available for desktop users only, Mozilla plans on rolling it out for mobile users as well, to ensure they too encounter fewer secure connection errors.
