How am I connected to VPN in my Firefox?

VPN
1

I have a desktop Windows PC and it has Firefox installed. I can enter all of the restricted sites (Twitch is banned in Turkey, for example). I do not have any VPN installed nor do I have any Firefox extensions. I checked settings and there is nothing indicative of VPN being enabled.

How the hell do I see these sites? I tried on my Mac laptop and same settings do not allow me to enter to those sites.

Is menu > Settings > Privacy and Security > DNS Over HTTPS enabled? That might get around some blocks, if they’re DNS-based

YES! It is actually DNS Over HTTPS. It is not Active by default on Mac so enabling it solved it.
