Hello, Thank you for contacting Mozilla VPN Support! The Mozilla VPN is compatible with Windows 10 (64-bit only), macOS(10.14 and up), Android (version 8 and up), iOS (12.0 and up), and Linux (Ubuntu-only) devices. You can download the VPN from vpn.mozilla.org. You’ll be prompted to sign up/in to your Firefox Account. Once you download the client, the installer should guide you through the rest. After you've installed it, open the client (by searching your device for Mozilla VPN), flip the switch to On, and you're good to go! It'll cover any internet activity on the device while it is turned on, including your browser activity. Let me know if you run into any issues along the way.
