## Description

The Onion Search Engine Chrome extension empowers users to seamlessly search both the conventional internet and the onion network (Tor/deep web/dark web) while ensuring complete privacy. It respects user confidentiality by eliminating cookies, JavaScript, third-party, or external code, thereby preventing any form of tracking or spying.

By setting Onion Search Engine as your browser's default search option, you gain direct, secure access to hidden and surface web content alike. Searching the onion network requires a Tor browser or a VPN compatible with Tor, ensuring anonymous navigation. With a simple keyword prefix "onion", users can instantly query the onion network without changing default settings. This extension is an essential tool for privacy-conscious users seeking comprehensive web search capabilities across open and hidden web layers.
