Following our publication Tor network in Firefox and Chrome, where we describe how to add the Tor network to Linux distribution browsers, here we will see how you can add a Tor network to Firefox running on Windows.
You must first install the Tor proxy service on your system. Unfortunately, torproject.org no longer has a standalone Tor binary for Windows. So you will need to install the entire Tor Browser Bundle. Download it from here.
When the file is downloaded, right click on it and Run as Administrator. Finish the installation and note where you installed the application.
Caution: Do not install Tor under a user's folder, but in dir with your other applications.
Then we need to configure Tor to run as a service. Open Command Prompt as administrator. Type cmd in the Windows search and the black icon that will appear when you first right-click and run it as an administrator (Run as Administrator).
When it opens run the following commands, adding the folder where you installed the application to:
cd C: \ Program Files \ Tor Browser \ Browser \ TorBrowser \ Tor
tor.exe -service install
That being said, the Windows you are using will now use the Tor network natively.
