A U.S. judge denied Mozilla’s request to intervene in a criminal case related to Playpen, a child pornography site shut down by the FBI last year. Mozilla sought to force the government to reveal the software flaw, arguing it could put millions of users at risk. It petitioned the court to be provided with the vulnerability details no less than two weeks before the defense received them, in order to engineer a patch. The FBI had control of Playpen for almost two weeks in early 2015 and used the Tor anonymity network to mask its true IP address.”]
