Looks good. When you write:
"Tor Browser, a fork of Firefox that isolates activity between Tor
circuits and disables a broad set of browser tracking vectors"
I cringed a bit when reading "disables" because that sounds like we
solve our problems by just disabling features which is not really the
case and gives kind of a negative connotation as this automatically
implies breakage. While it's true that we indeed do outright disable
some of those vectors it's only the last resort and for a lot of them
out there we can avoid that. That is we neuter the tracking potential
while keeping the functionality in place as good as we can.
Might be worth getting that point across if possible.
