Care to explain in detail how can TOR browser be deanonymized ? I know a story about the worst persons on earth and their servers were caught by FBI , which injected a malware via Javascript, so any of the maniacs who clicked on the video links there, were fully deanonymized. Let me remind you this was back in 2013 and mainly Windows users were caught. Now the TOR users, are using TAILS an OS which don't leave traces that you actually used it. Still I have heard stories of people claiming TOR can be deanonymized but without solid proof as evidence, so I would like to hear more in this regard as  a TOR user myself not via TAILS but via some other Linux distro.
