Review of Tor Browser: Protect Your Privacy and Surf Web Safely

Tor is an acronym that stands for The Onion Router. While the name suggests it is a router, it is actually a browser. Tor is the browser that stands for anonymity and privacy on the Internet. This review of Tor talks about how Tor works and how it provides anonymity when you are browsing the Internet.

Tor vs. Other Browsers

While Internet Explorer and Google Chrome offer the feature where you can browse anonymously (InPrivate and InCognito modes), they still lag behind when intermediaries are sitting between source and destination of web traffic. When you browse the web, send an email or download audio/video or anything, data is sent in the form of packets.

Each data packet has a header that tells about the source and destination of the data packet. Even if you are using an encrypted connection, the packet headers are vulnerable. Anyone sitting between the source and destination can read the packet header to know about you and your browsing habits. The people snooping include your ISPs, ad agencies and sometimes even the government agencies. As such, your browsing and what you see on the Internet is affected by the information others have gathered about you.

Why do you need Tor & Why

Tor has been developed with a total concentration on the privacy of users. People use Tor to send confidential emails. The high-level security of Tor makes it impossible for hackers to know the origination of emails and thereby the location of the sender. Following are some uses of Tor that make it clear as to who all need the safest browser available on the planet:

  1. You can send data anonymously.
  2. You can surf the web without leaving any traces as the traces are deleted as soon as data is forwarded from one relay to another. I will come to relays in a moment – in the next section.
  3. You can view the websites that are otherwise censored in your country – because the ISPs won’t know what you are trying to access.
  4. You can host websites that will be difficult to censor because nobody knows who is hosting the website.

There are many uses of Tor – especially in a world where user privacy has been under the prying eyes of different ad agencies, social networks, and government agencies. Also, your ISPs intercept your connection requests before you actually connect to a website. Using Tor, you won’t leave any data for such agencies.

The Tor Relay Network – How Tor Works

Tor Network works on a network of relays formed by people who have volunteered for the project. Unlike other browsers that have fixed routers that receive data packets to forward them to their destinations, Tor browser uses a number of relays. To be clearer, here is the procedure:

  1. When you enter a URL in Tor address bar, a random route is formed using the relay computers in the Tor network.
  2. Each relay computer in the network works as a router. It receives data packets, forwards it to the next relay computer in the network after deleting information about the previous router.
  3. Once the data packet leaves the relay computer, any information about the data packet is removed from the relay computer.
  4. Approximately every ten minutes or so, a new relay is set up to further protect your privacy.

The below figure shows how Tor works:

The aim is clear – to create a maze of relays so that all the information about the original source is lost in the network. This makes it impossible for the scripts on the destination website to track who sent the request/data and from where.

What Is The Tor Bundle

When you download the Tor bundle, you get three essential programs:

  1. Vidalia graphical Interface
  2. Tor Browser
  3. Tor Button

When you first download the Tor bundle, you are required to extract the files. You do not need any kind of installations. This means you can carry the extracted files on a USB drive for use with any computer running any kind of operating system.

Once you have extracted the Tor Browser bundle, you find an executable that says “Start Tor Browser.Exe”. When you double-click this file, it launches Vidalia graphical interface. Other than launching Tor after creating a Tor relay network, the graphical interface lets you:

  1. Change the default settings for Tor browser
  2. View the computers acting as a relay in the Tor network
  3. Check out the bandwidth
  4. Start and stop Tor browser (connect and disconnect the Tor connection)
  5. Check out the help files and About

Once the relay is set up, you get the Tor browser as shown in the first image in the above section. The Tor button is located before the address bar and it allows you to allow/block cookies from running on the webpage you are visiting. You can also change your preferences using the Tor button. If you wish, you can start a new session (a new relay) using the Tor button.

Note that you need to download all the components using the Tor bundle. You cannot and should not try to download and use individual components as your computer may become unstable.

How To Use Tor Browser

As with any browser, you just enter the URL in the address bar and hit enter to visit the website you want. The bar next to the address bar is a Quick search bar. It allows you to select websites such as Google, Amazon, Bing, Twitter, Wikipedia and more. After selecting the website that you wish to search, enter the search term and hit the Enter key.

You can click on the Tor button (onion icon towards the left of Tor browser) to set up Tor cookies and other preferences.

You can further customize your preferences about privacy by selecting the behavior of Tor when it comes to InCognito browsing. Click on the Tor Browser button on the title bar of Tor Browser and in the resulting sub-menu, click on Options and again on Options. In the resulting dialog box, click Privacy tab. In this tab, you can set whether you want to save cookies, download history, passwords, etc. You can also set Tor mode where “websites should not try to track you” (Though this is not very reliable as ad agencies and especially government agencies will continue to track you irrespective of your will).

Drawbacks Of Tor Browser

There is only one – the browser gets slower at times. This is because of the fact that the data packets are routed through a good number of relay points in the Tor browser. I could not find any other negatives while browsing with Tor. Also, on some sites, you may have to allow scripts using the S icon just before the address bar. Sites such as Facebook and Twitter make extensive use of scripts so you may face problems if you run Tor with scripts blocked. You can toggle blocking/allowing scripts using the S button.
