Tor Browser is part of the wider Tor project. It is based around Mozilla Firefox, using a modified version of that program, but comes with the added privacy benefits that are the main focus of the Tor project. This makes the browser the ideal choice for security-conscious web surfers.

The browser can be downloaded from the official Tor website. The site provides all the information necessary when it comes to obtaining the program. In addition, the site offers the browser's open source, for more code-savvy users who are interested in expanding upon the main software.

Installing the software could not be easier. Once the relevant file has been downloaded, execute it and it will extract the browser into a folder of its own. From there, simply run the browser and you will be ready to go.

The browser is designed to protect the user's privacy by preventing any potential observers from keeping an eye on websites visited. In today's world, where more and more people are conscious about cyber-surveillance, the browser offers an appealing way of surfing the Internet in private.

At the present moment, the browser is available for Windows, Mac, Linux and Android. In short, most (but not all) of the popular platforms are currently covered by the software.

Yes, Tor is completely free to download, install and use. The open source is also available for no charge, giving users the freedom to alter and expand upon the software as much as they are able.

While the browser does offer greatly enhanced privacy, users will still need to follow certain steps to ensure that their browsing is secure. These include viewing only HTTPS versions of sights, avoiding plugins, and be careful when downloading documents that may engage with other, less secure pieces of software.

As noted above, users of the browser will still face some security concerns. There are also wider moral concerns about the existence of the software, as the browser can be used to mask illegal activity.

It is not in itself illegal to use the browser. However, doing so may potentially leave the user open to suspicion, as the browser can be used as a means of committing illegal acts online. Anyone who plans to use the browser should fully research the legal and moral controversies that surround Tor.

Unfortunately, yes. Tor has a tendency to run slowly, as a result of the indirect manner in which it handles the user's Internet traffic. Those planning on using Tor should bear this in mind and consider whether they have the patience to use it. More dedicated users, on the other hand, will find the lags a worthwhile trade-off for anonymity.
