Want Tor to really work?
You need to change some of your habits, as some things won't work exactly as you are used to.- Use the Tor Browser
Tor does not protect all of your computer's Internet traffic when you
run it. Tor only protects your applications that are properly configured to
send their Internet traffic through Tor. To avoid problems with Tor
configuration, we strongly recommend you use the
Tor Browser Bundle. It is pre-configured to protect
your privacy and anonymity on the web as long as you're browsing with the Tor
Browser itself. Almost any other web browser configuration is likely to be
unsafe to use with Tor.
- Don't enable or install browser plugins
The Tor Browser will block browser plugins such as Flash, RealPlayer,
Quicktime, and others: they can be manipulated into revealing your IP address.
Similarly, we do not recommend installing additional addons or plugins into
the Tor Browser, as these may bypass Tor or otherwise harm your anonymity and
privacy. The lack of plugins means that Youtube videos are blocked by default,
but Youtube does provide an experimental opt-in feature
(enable it here) that works for some
videos.
- Use HTTPS versions of websites
Tor will encrypt your traffic
to and
within the Tor network, but the encryption of your traffic to the final
destination website depends upon on that website. To help ensure private
encryption to websites, the Tor Browser Bundle includes HTTPS Everywhere to force the
use of HTTPS encryption with major websites that support it. However, you
should still watch the browser URL bar to ensure that websites you provide
sensitive information to display a
blue or
green URL bar button, include https:// in the URL, and display the
proper expected name for the website. Also see EFF's interactive page
explaining how Tor
and HTTPS relate.
- Don't open documents downloaded through Tor while online
The Tor Browser will warn you before automatically opening documents that are
handled by external applications. DO NOT IGNORE THIS WARNING. You
should be very careful when downloading documents via Tor (especially DOC and
PDF files) as these documents can contain Internet resources that will be
downloaded outside of Tor by the application that opens them. This will reveal
your non-Tor IP address. If you must work with DOC and/or PDF files, we
strongly recommend either using a disconnected computer,
downloading the free VirtualBox and
using it with a virtual machine image
with networking disabled, or using Tails.
Under no circumstances is it safe to use
BitTorrent
and Tor together, however.
- Use bridges and/or find company
Tor tries to prevent attackers from learning what destination websites you
connect to. However, by default, it does not prevent somebody watching your Internet
traffic from learning that you're using Tor. If this matters to you, you can
reduce this risk by configuring Tor to use a Tor
bridge relay rather than connecting directly to the public Tor network.
Ultimately the best protection is a social approach: the more Tor
users there are near you and the more
diverse their interests, the less
dangerous it will be that you are one of them. Convince other people to use
Tor, too!
Be smart and learn more. Understand what Tor does and does not offer. This list of pitfalls isn't complete, and we need your help identifying and documenting all the issues.
