Protect your online identity with IP-based access control.
This extension provides a critical security layer for the Chrome browser, allowing you to restrict access to sensitive websites (such as crypto exchanges, banks, or work panels) to a specific IP address. If your VPN disconnects or your IP changes, Kill-Switch immediately cuts off access and closes the relevant tabs to prevent any leaks.
- 🔒 IP Lock: Specified sites open only with the IP address you define.
- ⚡ Instant Reaction: Automatically closes open tabs the moment your IP changes.
- 🛡️ Fail-Closed Security: If the internet is unstable or the IP cannot be detected, all access is locked down for maximum security.
- 🕵️ WebRTC Protection: Prevents your real IP from leaking via the WebRTC protocol.
- 📝 History: Displays a log of blocked access attempts.

This tool is designed to enhance browser security but is not a complete replacement for an OS-level "Kill-Switch" or hardware firewalls. For 100% security in highly sensitive cases, please also ensure you use your VPN's built-in security settings (Network Lock).
