This also requires the user not being very sophisticated. If you load
up html emails full of web-bugs, javascript, and your normal browser
pointed at Tor, then I believe most of what 'SR' says is correct. I
don't believe this is true for Tor Browser users, but I welcome
research and proof otherwise.  Also, we'll fix any leaks found.

If the 'wiretappers ball' has shown anything, there are plenty of
well-marketed solutions for surveilling and stalking unsuspecting
users. Ask them how well they work against even moderately
sophisticated users, like junior agents of foreign agencies, you'll get
a different answer and lots of weasel words.

I've seen these tools used by abusers against their victims as
well. If you can infect the operating system, such as carrier IQ,
keyloggers, software to 'know where your kid/spouse/dog are at all
times', and the like, you've won. Tor alone cannot protect you if your
operating system is compromised. Tails can help in these situations. If
your hardware is compromised, tails can still help, with caveats.

If you're trying to be anonymous with Tor while someone with an
automatic weapon is standing behind you, you've lost in many ways.

It's all about understanding and managing risks.
