How do I know Firefox is using the VPN?

With the desktop app connected, check our what-is-my-ip tool. The IP should match your chosen server.

Can I protect only Firefox?

A system VPN covers all apps. Some platforms support split tunneling — see /vpn-split-tunneling. Browser-only protection on Chromium is covered in /chrome-vpn.

Does VPN help with Firefox fingerprinting?

It changes your IP, which removes one signal. It does not replace Firefox’s own privacy settings or container tabs.

Use the Linux desktop client, connect, then launch Firefox as usual.
