It is my understanding that the point of whonix is to use tor at a fundamental level so the OS doesn’t even know the computer’s local IP. So my question is what difference does it make whether you use Tor browser or plain firefox inside whonix ? Also does using tor browser mean that you’re using tor “twice” in the sense that tor browser will wrap packets to go through tor and whonix will rewrap those packets a second time ?

Have a nice day,
