Onion Browser Button is a lightweight Firefox add-on designed to facilitate easy access to the TOR network directly from your browser. This unofficial extension allows users to browse under a TOR proxy, enhancing online privacy and anonymity. However, it is crucial to note that it is not affiliated with the official Tor project and operates independently. Users must enable the 'Run in Private Windows' feature in Firefox for the add-on to function correctly, as the proxy settings will not activate otherwise.

To use Onion Browser Button effectively, users must ensure their PC or Mac is connected to the TOR network prior to utilizing the add-on. Detailed instructions are provided for connecting to TOR, including downloadable patches for both Windows and Mac systems. The setup process involves running specific scripts to establish a TOR connection. Once connected, users can easily toggle their TOR connection and manage their identities through the add-on's options.
