Tor Browser is a specialized web browser designed to provide users with enhanced privacy and anonymity while surfing the internet. Developed by the Tor Project, a non-profit organization, Tor Browser is built on Mozilla Firefox but with significant modifications to protect user data from being tracked or monitored by external entities.
History of Tor Browser
Tor Browser has its roots in a project that was initially funded by the U.S. Naval Research Laboratory in the mid-1990s. The goal was to create a network that would allow secure and anonymous communication over the internet. The Tor Project was officially launched in 2002, and the Tor Browser as we know it today was released in 2008. Over the years, Tor Browser has evolved to become one of the most popular tools for online privacy.
Importance of Privacy and Anonymity Online
In today’s digital age, privacy and anonymity have become critical concerns for internet users worldwide. With governments, corporations, and hackers constantly seeking to monitor online activities, tools like Tor Browser offer a vital means of protecting one’s personal information and maintaining privacy online.
Overview of Tor Project
The Tor Project is a non-profit organization dedicated to research and development in the field of online privacy and anonymity.

Technical Specifications
How Tor Browser Works
Tor Browser functions by routing your internet traffic through a network of volunteer-operated servers, known as nodes. This process is called onion routing, and it involves multiple layers of encryption to ensure that each node in the network only knows the previous and next nodes in the path, making it nearly impossible to trace the original source of the traffic.
1. Onion Routing
Onion routing is the backbone of the Tor network. It involves wrapping data in multiple layers of encryption, much like the layers of an onion. Each layer is peeled away by a different node in the network until the data reaches its final destination. This method prevents any single point in the network from knowing both the origin and the destination of the data.
2. Encryption Layers
Tor Browser uses several layers of encryption to protect the privacy of its users. When data enters the Tor network, it is encrypted multiple times. Each relay in the network decrypts a single layer to reveal the next relay, and only the final relay decrypts the innermost layer to reveal the destination data. This ensures that the data remains secure throughout its journey.
Supported Operating Systems
Tor Browser is compatible with multiple operating systems, including Windows, macOS, Linux, and Android. This broad compatibility ensures that users across different platforms can benefit from enhanced privacy and security while browsing the internet.
Compatibility with Add-ons and Extensions
While Tor Browser is based on Mozilla Firefox, it is not recommended to install additional add-ons or extensions, as they can compromise the privacy and security features of the browser. However, some users may choose to use specific add-ons, such as NoScript, which is included by default to block potentially malicious scripts.
Uses of Tor Browser in Different Industries
