FoxyVPN - Unofficial Firefox VPN client

FoxyVPN signs in with a Firefox account, obtains a proxy pass from Mozilla's Guardian service, and carries the whole device's traffic through Firefox VPN's Fastly edge over an HTTP/2 tunnel. It is a native Kotlin app with a Jetpack Compose (Material 3) UI.

🚀 How to use?

1. Get a Firefox account. If you do not have one, create it for free at accounts.firefox.com.
2. Install the APK from the Releases page.
3. Sign in with that account's email and password.
4. Pick a location and tap the power button.

Note

No subscription is required. FoxyVPN runs on the free 50 GB of monthly VPN traffic Mozilla includes with a Firefox account for browser users, which is the same allowance the Firefox browser's built-in VPN uses. Once the allowance is used up for the month, connections stop working until it resets.
