Back in the day, there use to be a configuration option in Tor Launcher for strict firewall allowing only port 80 and 443 but it's not the case anymore.

It's a complex word that can mean many different things ("*Is this about configuring my firewall?*") and doesn't relate to anything in Tor Launcher down the road.
