Extension Metadata
About this extension
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.
- Click the SuperTunnel icon in your toolbar to open the popup.
- Choose Remote API (and enter your controller endpoint/token) or Local proxy (enter host & port).
- Toggle the Connect switch to activate the proxy.
