Is Free Proxy for Surfing safe?

Clean risk

VPN routes all browser requests through Hiddence proxy servers using hardcoded shared credentials.

When the VPN is enabled, the extension applies a Hiddence proxy to all browser URLs and adds a Basic proxy authorization header. The username and password are embedded in the extension code and reused for proxy authentication.
