USB-Tethering ignores Advanced Privacy and DNS settings

With my FP4 the settings I made in Advanced Privacy and Private DNS are ignored when I use USB-Tethering.

If I lookup the IP address and DNS provider on the /e/ Browser I see exactly the settings I chose. If I do the same on my laptop while USB-Tethering is used I see the settings of the provider of the SIM card I use for mobile data.

OS-Version: 3.1.4-a14

Settings in Advanced Privacy:

  • App Trackers: Denied
  • Geolocation: Exposed
  • Real IP Address: Hidden

Settings in Private DNS: Private DNS provider

Can anyone confirm this?

Is it a feature or a bug?
