Tor Browser Bundle


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 without needing to install any software. It can run off a USB flash drive, comes with a pre-configured web browser and is self contained. If you would prefer to use your existing web browser, install Tor permanently, or if you don't use Windows, see the other ways to download Tor.

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 (version 1.0.1, 13 MB)

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.

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.


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.bat 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.

Once you are finished browsing, close any open Firefox windows by clicking on the (6). Vdalia and Tor will automatically close. For privacy reasons, the list of webpages you visited and any cookies will be deleted. To use it 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.
