It’s better to use Whonix or Tails if you want to use TOR browser securely. If I ever had to use Windows again it would not be for anything private.

I’m certain there are people who use Tor in a way that it would make sense to use a secure OS.

But I use Tor to get around stupid public wifis and suchlike that have content blockers. I’m not scared that the police are going to beat the shit out of me so I just use Windows or Android.
