Can I choose or change my IP address on Firefox Private Network?
When you connect using the Private Network browser-level protection (the Firefox extension), your IP address will change to a Cloudflare server IP address. You will not be able to choose the server location.
The full-device offering (VPN) allows you to choose a server location. Your local IP address will change to your chosen server’s IP address while you’re connected. See this Subscribe and install Firefox Private Network Device-level protection for more details.
