Close duplicate tabs in the current browser window with one click. Duplicate Tab Sweep is a lightweight Chrome extension designed to help users quickly clean up duplicate tabs in the current browser window. With a single click, the extension scans open tabs, detects multiple tabs with the same URL, and closes the duplicates while keeping the first matching tab open. The popup provides a simple overview of the number of tabs currently open in the active window and how many duplicate tabs have been found. Users can scan first to review the duplicate count, then run the cleanup action when ready. This makes it useful for reducing tab clutter, improving organization, and managing browsing sessions more efficiently. The extension focuses only on tab deduplication in the current window. It does not collect, store, transmit, or share personal information. It does not connect to remote servers or use external services. All scanning and tab-closing logic runs locally in the browser. Duplicate Tab Sweep requires access only to tab information so it can compare tab URLs and close duplicates. It is intended as a simple, privacy-conscious browser utility with minimal permissions.
