How to run Multiple Tor Browser instances on windows?

Question

I am trying to run multiple instances of Tor Browser on Windows with different torrc configuration and different ip addresses.

Tor Browser version: 10

OS: Windows 7

I have modified torrc file with SocksPort and ControlPort, also I have modified extensions.torlauncher.control_port and network.proxy.socks_port on the browser.

I am able to open multiple windows from the same TBB but unable to open separate instances with separate torrc config.

I have tried these options, but they don't work anymore.

Answer 1

Make a copy of your installed Tor directory. (For example copy to Tor Browser2) Edit the file \Tor Browser2\Browser\TorBrowser\Data\Browser\profile.default\prefs.js In my example the socks port is 9250, the control port is 9251 user_pref("network.proxy.socks_port", 9250); user_pref("network.security.ports.banned", "9050,9051,9250,9251"); user_pref("extensions.torlauncher.control_port", 9251);

Here you can see that 2 Tor instances are running.
