I didn't find any that seemed likely to reveal any system information. On the other hand, I may have missed a case, and I can imagine more privacy- violating messages might be introduced in the future. So, to be safe, I wrote a patch that censors any messages when "privacy.resistFingerprinting" is enabled: https://github.com/arthuredelstein/tor-browser/commit/21792 -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/21792#comment:9> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online _______________________________________________ tor-bugs mailing list tor-bugs@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-bugs
