Is VPN TunnelFly safe?

Low risk

VPN TunnelFly hands its proxy login credentials to any website that sends an HTTP basic-auth challenge, not just its own proxy server.

The extension listens for the browser's authentication prompt on every site, not only on its VPN proxy connection, and never checks whether the request actually came from the proxy. When any website responds with an HTTP 401 or 407 basic-auth challenge, the extension automatically supplies your stored proxy account username and password to it through the browser's built-in auth flow, with no prompt or confirmation shown to you.
