Hello! To use the VPN, all you need to do is sign in and download the client from vpn.mozilla.org. Once you've installed it, you just need to open it, sign in with your Firefox Account, and hit the switch to turn it On. You can verify the VPN is active or not by opening the VPN app and checking the connection status. When it shows you are connected, all your internet traffic will get encrypted and routed through one of our secure servers. The VPN will cover any internet activity on the device regardless of the browser you are using. I hope you find this helpful,
