This is a list of Seldomly Asked Questions pertaining to Tor Browser 3.x.

WARNING This page is about Tor Browser 3.x, which is SERIOUSLY OUTDATED. It exists only because of historical significance. Users should refer to TorBrowserBundleSAQ for information.

How do I make Tor Browser 3.x use the tor that is already running on the system?

Are you sure you want to do this? The Tor Browser runs tor using different ports so it can co-exist happily with the tor process already running on your system. Furthermore if you are running a relay, it may be better to run another tor instance for all of your personal Tor usage.

WARNING Using Tor Browser in this manner is NOT OFFICIALLY SUPPORTED. If this does not work or randomly clobbers your torrc, you are on your own.

If you are using the Tor Project's Debian/Ubuntu packages (You ran apt-get install tor at some point):

  1. Add the user you will be running Tor Browser as to the debian-tor group.
  2. Set the following environment variables:
       export TOR_SKIP_LAUNCH=1
       export TOR_SOCKS_PORT=9050
       export TOR_CONTROL_PORT=9051
       export TOR_CONTROL_COOKIE_AUTH_FILE=/var/run/tor/control.authcookie
  3. Start Tor Browser.
       $ ./

If you wish to use password authentication for the control port, you will need to wait till #9936 is fixed.
