Tor Browser 8.0 lacks fingerprint hiding feature
I recently surfed to https://panopticlick.eff.org/ and looked out for my Tor Browser Bundle fingerprint.
I'm using TBB on my 64-bit Linux machine, so the result was Mozilla/5.0 (X11; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0 instead of some kind of "faked" fingerprint that shows that my machine would be a Microsoft Windows computer.
I ran the same test in the previous version of TBB that I had before the update procedure gave me the 8.0 version, I didn't had the bug that my original browser fingerprint was leaked to the server I was connecting to.
I downloaded TBB 8.0 also as a fresh instance from torproject.org with the same result.
This breaks anonymity because a web server knows your real system & architecture. I don't know if this is only the case for the Linux variant of the browser because I don't have access to Mac OS or Windows machines right now. I furthermore only tested the 64 bit variant.
I hope that this is not one of the new "features" that were included in version 8.0 ...
