The VPN works through Wi-Fi and mobile networks it is just a proxy not an inbuilt VPN

You can read about it here if you search [VPN]

The KB article explains what it is. The built-in VPN in Firefox for Android is free with no subscription options. It does however have a monthly 50GB data usage cap. However unlike the built-in VPN feature on desktop Firefox it currently does not have a way to manually change server location.

These articles are about the built-in VPN in desktop Firefox. https://www.firefox.com/en-US/features/browser-with-built-in-vpn-secure-browsing/ https://blog.mozilla.org/en/firefox/built-in-vpn/

The built-in VPN is only in the Firefox web browsers for desktop and Android and does not cover the whole device like standalone VPN's do. It is also not a full VPN like how the subscription based standalone Mozilla VPN app is. Like most built-in browser VPN's and Extension VPN's the built-in VPN in Firefox actually routes your browsing traffic through a proxy network that replaces your IP address before it reaches a website. The sites you visit see the proxy’s IP address rather than your own.
