A Tor browser is a web browser designed to protect the user’s privacy and security by sending internet traffic through a network of servers known as the Tor network. This network is designed to hide the user’s identity and location by encrypting data and routing it through multiple randomly selected relays. The Tor network was developed by the US Naval Research Laboratory and is now maintained by the Tor Project, a non-profit organization.

The Tor browser is based on the Firefox browser and is available for Windows, Mac OS X, and Linux. It is free and open source software, allowing anyone to inspect its code. The Tor browser is designed to provide anonymous internet access, allowing users to browse the web without revealing their identity or location. Using the Tor browser, users can visit websites, send emails, and chat with friends without being monitored or tracked. It also provides access to websites that are blocked or censored in certain countries.

Tor also provides access to the so-called dark web, a part of the internet that is not accessible through traditional search engines. The dark web is home to online markets selling illegal goods, as well as other activities which are often associated with criminal activity. It is important to note that accessing the dark web is not illegal, but some of the activities that take place there may be.
