7.0 FAQ and Conclusion

Tor is an extremely well tested and well maintained piece of software. The Tor anonymity network is used by hundreds of thousands of people worldwide, and continual improvements have made it increasingly stable and secure. Although the explanations in this chapter may seem complex, in many cases you will not have to read past Section 2.0 How to Access the Tor Anonymity Network in order to get Tor working properly.

Mansour has carefully read Chapter 8 of the How-to Booklet, about censorship circumvention, and has just finished working through the Tor Guide. He nonetheless has a few questions for Magda, who has been using Tor for years.

Q: Why should I use Tor, anyway?

A: Good question. Tor is a great tool if you need to circumvent Internet censorship in order to access certain websites. It's also handy if you don't want your Internet Service provider to know what websites you're visiting, or if you don't want those websites to know where you're coming from.

Q: What's the difference between using the Tor Browser and the version of Tor that I have to install?

A: The Tor Browser can be extracted to a USB memory stick and accessed from any computer you use, including your own. You won't need to install it again. On the other hand, if you actually install the Vidalia bundle on your computer, Tor will work a little bit faster. Plus, assuming you were already a Firefox user, you'll have access to your existing bookmarks and add-ons when you're using Tor.

Q: I have error messages in the 'Message Log' that I don't understand. What should I do?

A: See if those messages are in the Tor FAQ wiki. You could also press the 'Help' icon in the Vidalia interface and take a look at the 'Troubleshooting' section.
