Ulbricht was caught via poor OPSEC and not via a Firefox/Tor 0day afaik. Though there was/is speculation that a Firefox/Tor 0day was used to bring down some Tor markets and possibly to locate the Silk Road's server. Silk Road 2.0 was brought down in like a few months, which could indicate such a 0day existed. Or that it was ran by some former Silk Road staff members who got doxed when Silk Road 1.0 was shut down.
