Duplicate Tab Closer

Duplicate Tab Closer is a simple and privacy-friendly Chrome extension that helps users identify and close duplicate tabs with one click. When you open the popup, the extension scans all open tabs, detects duplicates based on their normalized URLs, and shows a clean list of repeated tabs.
Users can choose to close all duplicate tabs manually or enable an optional auto-close feature that removes duplicates automatically the next time the popup is opened. All processing is done locally on the user’s device, and the extension does not collect, store, or transmit any personal data.
This tool is designed to improve browser organization, reduce clutter, and save memory by ensuring users do not accidentally keep multiple identical tabs open. The interface is simple and lightweight, allowing anyone to tidy up their browsing session quickly and efficiently.
