But the Firefox version is new, including the html5 canvas stuff. So I think this is still a plausible direction to consider. A search for 'zemana firefox' brings up several cases like https://support.mozilla.org/questions/687961 that look related -- people have had problems with the interactions between these two programs in the past. > I guess inside the rerouting net is a kind of automatic tool to spy Tor > users and, in addition, the (humans) operators my pick users at will for > additional checks. Just my guess. Well, one of the great features of Tor Browser is the deterministic build process: https://blog.torproject.org/blog/deterministic-builds-part-one-cyberwar-and-global-compromise https://blog.torproject.org/blog/deterministic-builds-part-two-technical-details which basically means that anybody can produce a byte-for-byte identical version of the Tor Browser download that you have -- and many people reproduced the Tor Browser 3.6.3 and 3.6.4 versions that you have (assuming of course that you fetched the real one). So that means you can grab all the source code (mostly of Firefox) and be sure that it's actually the thing you're running: https://trac.torproject.org/projects/tor/wiki/doc/TorBrowser/Hacking#BuildingtheTorBrowser Now, I know it isn't fun to look through all of Firefox for compatibility problems between it and your other Windows program. But the point is that anybody can do it. So hopefully it is an answer to your above conspiracy concerns -- if you think there's a screen capture feature in Firefox, find it! > Hope more users will start to use Zemana and other anti-spyware and more > reports about this problem arrives. Hey, good thinking. Are there any other Zemana users here? I have never heard of it, so maybe nobody else has either. --Roger -- tor-talk mailing list - tor-talk@lists.torproject.org To unsubscribe or change other settings go to https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
