Re: [tor-talk] browser fingerprinting
Yes, of course js is not at all the cause of the problems described in
this thread, strange that this very wrong idea is still popular.
JS can not prevent you from hacking yourself if you like which is what
the links provided here are about.
That's even the contrary, you can not hide js code, whatever obfuscation
means you are using it's very easy to see what it is doing.
But you can run js code as a standalone app, ie without loading the code
from the outside and using third parties to check that you have the
correct one, because loading the code is the only issue about js.
Assuming that js devs are following good practices, if the code is
sandboxed and you can not access js objects via other means (like DOM
nodes) then there is no way you can hack into it.
And for sure js can not access anything on your computer outside of the
browser's world (ie outside of what you have authorized it to access)
This is what I have tried to explain for this project here

inside browsers, so a js app)

And yes, sandboxes and firewalls do seem like a great idea, for tolerating

on making them both effective and usable. We need more people in the
world working on that.
