HCOS - Hide Chrome Omnibox Suggestions

HCOS is a Chrome extension designed to enhance your browsing privacy and streamline your search experience by hiding the historical search suggestions that appear when you focus on the address bar (Omnibox) on new tab pages. It works by deleting Google search records related to your typed queries, ensuring no suggestions are displayed from your past searches.

Additionally, HCOS allows you to customize your browsing further by enabling the addition of custom website URL prefixes via the extension's options page. This feature provides a tailored and distraction-free browsing environment by controlling which URL suggestions you want to see or avoid. Simple to install and easy to use, HCOS improves your Chrome address bar usability without compromising performance.
