Tab Tunnel Autor: Digitalhen

Tab Tunnel automatically routes browser tabs through a SOCKS5 proxy based on the domains you configure. Navigate to a matching site and that tab's traffic — including all subresources and DNS — goes through your proxy. Every other tab stays on your normal connection.

Set it up once and forget about it. No app to toggle, no split tunneling to configure.

Use cases:
- Watch foreign TV (BBC iPlayer, ITV) from anywhere
- Protect banking and financial sessions with a VPN tunnel
- Route only sensitive tabs through a VPN, keep everything else fast

Features:
- Per-tab proxy routing via Firefox's proxy.onRequest API
- DNS leak protection (DNS resolves through the proxy)
- Add or remove trigger domains from the popup
- Zero overhead on non-proxied tabs

Bring your own SOCKS5 proxy, or use the package available at https://github.com/digitalhen/tab-tunnel with NordVPN/WireGuard.
