Fingerprinting Firefox users with cached intermediate CA certificates (#fiprinca)

Fingerprints Firefox through its cache of intermediate CA certificates. Image loads from servers with incomplete certificate chains succeed only when the missing intermediate is cached. Probes covering over 300 intermediates reveal browsing-related information and can link private browsing to a normal profile; deliberately populating the cache could also create a supercookie.
