Tor Browser Bundle

Torbutton


Torbutton is the component in Tor Browser Bundle that takes care of application-level security and privacy concerns in Firefox. To keep you safe, Torbutton disables many types of active content.
Now that the Tor Browser Bundle includes a patched version of Firefox, and because we don't have enough developer resources to keep up with the accelerated Firefox release schedule, the toggle model of Torbutton is no longer recommended. Users should be using Tor Browser Bundle, not installing Torbutton themselves.

What is the Tor Browser Bundle (TBB)?

The Tor software protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, it prevents the sites you visit from learning your physical location, and it lets you access sites which are blocked.
The Tor Browser Bundle lets you use Tor on Windows, Mac OS X, or Linux without needing to install any software. It can run off a USB flash drive, comes with a pre-configured web browser to protect your anonymity, and is self-contained.

Download Tor Browser Bundle

To start using the Tor Browser Bundle download the file for your preferred language. This file can be saved wherever is convenient, e.g. the Desktop or a USB flash drive.
Tor Browser Bundle for Windows with Firefox Aurora (version 2.2.37-1)
The Tor IM Browser Bundle has been temporarily discontinued.
BETA: Tor Browser Bundle for Intel Mac OS X 10.5 and higher with Firefox Aurora (version 2.2.37-1, 28 MB)
BETA: Tor Browser Bundle for Linux with Firefox Aurora (version 2.2.37-1 (32-bit), 2.2.37-1 (64-bit), 24 MB)
ALPHA: Tor Browser Bundle alpha versions for Windows (2.3.12-alpha-2), Linux 32-bit (2.3.12-alpha-2) and 64-bit (2.3.12-alpha-2), and Intel Mac OS X 10.6 and higher (2.3.12-alpha-2) with Firefox
See our instructions on how to verify package signatures, which allows you to make sure you've downloaded the file we intended you to get. Also, note that the Firefox Aurora in our bundles is modified from the default Firefox Aurora; we're currently working with Mozilla to see if they want us to change the name to make this clearer.

Mac OS X instructions

Download the file above, save it somewhere, then click on it. Mac OS X will automatically unarchive it and you will have a TorBrowser application in your chosen language (for example, TorBrowser_en-US.app). Click the TorBrowser application to launch Vidalia. Once Vidalia connects to Tor, it will launch Firefox Aurora.

Linux instructions

Download the architecture-appropriate file above, save it somewhere, then run one of the following two commands to extract the package archive:

tar -xvzf tor-browser-gnu-linux-i686-2.2.37-1-dev-LANG.tar.gz

or

tor-browser-gnu-linux-x86_64-2.2.37-1-dev-LANG.tar.gz

(where LANG is the language listed in the filename).

Once that's done, switch to the Tor browser directory by running:

cd tor-browser_LANG

(where LANG is the language listed in the filename).

To run the Tor Browser Bundle, execute the start-tor-browser script:

./start-tor-browser

This will launch Vidalia and once that connects to Tor, it will launch Firefox. Do not unpack or run TBB as root.

Windows instructions

Extraction

Download the file above, and save it somewhere, then double click on it. Click on the button labelled "..." (1) and select where you want to save the bundle then click OK (2). At least 50 MB free space must be available in the location you select. If you want to leave the bundle on the computer, saving it to the Desktop is a good choice. If you want to move it to a different computer or limit the traces you leave behind, save it to a USB disk.
Click Extract (3) to begin extraction. This may take a few minutes to complete.

Usage

Once extraction is complete, open the folder Tor Browser from the location you saved the bundle.
Double click on the Start Tor Browser (4) application (it may be called Start Tor Browser.exe on some systems.)
The Vidalia window will shortly appear.

Once Tor is ready, Firefox will automatically be opened. Only web pages visited through the included Firefox browser will be sent via Tor. Other web browsers such as Internet Explorer are not affected. Make sure that it says "Tor Enabled" (5) in the bottom right corner before using it. To reduce the risk of confusion, don't run Firefox while using the Tor Browser Bundle, and close existing Firefox windows before starting.
If you installed the Tor IM Browser Bundle, the Pidgin instant messaging client will also be automatically opened.
Once you are finished browsing, close any open Firefox windows by clicking on the Close     button (×) (6). For privacy reasons, the list of webpages you visited and any cookies will be deleted.

With the Tor Browser Bundle, Vidalia and Tor will automatically close. With the Tor IM Browser Bundle you need to also close Pidgin by right-clicking on the Pidgin icon (7), and choosing Quit (8).

To use the Tor Browser Bundle or Tor IM Browser Bundle again, repeat the steps in "Usage".
Remember that Tor anonymizes the origin of your traffic, and it encrypts everything inside the Tor network, but it can't encrypt your traffic between the Tor network and its final destination. If you are communicating sensitive information, you should use as much care as you would on the normal scary Internet — use HTTPS or other end-to-end encryption and authentication.
