Description

A while back (https://bugzilla.mozilla.org/show_bug.cgi?id=1392841) a feature landed that implements racing between cache and network to get a resource loaded faster. I wonder whether that could be used to fingerprint users in a) a Tor Browser default context and b) outside of Tor Browser's permanent private browsing mode.
