SuperTunnel door SuperPlugs

SuperTunnel is an open-source browser proxy controller. The Firefox extension applies PAC scripts or fixed proxies through the WebExtensions proxy API, connecting to local proxies or remote controller backends.

• Multiple Modes: Use a local fixed proxy (HTTP/HTTPS) or fetch validated PAC / fixed-proxy profiles from a remote API.
• Authentication: Optional bearer-token authentication for secure endpoints.
• Live Diagnostics: Integrated Cloudflare trace health check reporting WARP status, Gateway, Cloudflare data center (colo), and proxy health.
• State Reconciliation: Persisted settings with automatic connection-state tracking and toolbar badge indicators.
• Privacy First: Affects browser traffic only and does not collect or transmit personal user telemetry.

1. Click the SuperTunnel icon in your toolbar to open the popup.
2. Choose Remote API (and enter your controller endpoint/token) or Local proxy (enter host & port).
3. Toggle the Connect switch to activate the proxy.
