VPN Master - Free HTTP and SOCKS Proxies

The "VPN Master" extension is a VPN solution based on two free proxy providers. You can select from these API servers and the extension finds a suitable proxy for you. The proxy type can be HTTP, SOCKS4, and SOCKS5.

When a new server is returned by the API, the extension validates your connectivity using the "checkip.dyndns.org" service. If the connection is not reliable, the extension resets the currently set proxy server and looks for other alternative proxies.

The following options are configurable:

1. GET requests support
2. POST requests support
3. Cookies support
4. Referer header support
5. User-agent header support
6. HTTPS support
7. Anonymity Level
8. Proxy Protocol
9. Country

There are two built-in tools in the popup:

1. Check DNS leakage
2. Check the external IP address
