Tor Browser 8.0 on Linux has user-agent
Mozilla/5.0 (X11; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0

This behavior can aid fingerprinting or vulnerability exploitation.

Tor Browser 7.x.x and before had one single Windows user-agent even on Linux platforms, only Android (Orfox) had other UA.

I suspect Windows/MacOS version is leaked through UA.

Why did the Tor Browser team release Tor Broswer 8.0 with such a critical bug?
