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?

Get a Firefox account. If you do not have one, create it for free at accounts.firefox.com.
Install the APK from the Releases page.
Sign in with that account's email and password.
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.
