# HOWTO MAKE IT WORK ?
#
# Required for windows user: you may want to have linux friendly shell already installed (Git-Bash is doing a fine job and easy to install)
# Then,
# Go to Tor Browser install directory ex: "C:\Programs\Tor Browser"
# Create and or copy this script there under the name "tbb_clone.sh" (name and path not important if you know what you are doing)
# Run the script ex: "bash ./tbb_clone.sh -n 4 -p ./Browser"
# This will create 4 copies of the "Browser" folder named "TBB1" to "TBB4"
# In each instance, start firefox.exe and test your ips ! http://ip-check.info
# Enjoy; thanks to https://tor.stackexchange.com/questions/2006/how-to-run-multiple-tor-browsers-with-different-ips/6401#6401
