Duplicate Tabs Closer is a powerful Chrome extension designed to help you manage duplicate tabs efficiently. It offers two main modes: an active mode that automatically closes duplicate tabs as they open, and a passive mode that allows users to view duplicates in a popup interface where they can manually close unwanted tabs.

The extension comes with a variety of customizable options such as prioritizing which duplicate tab to keep (older, newer, pinned, HTTPS), whitelist management, and the ability to ignore URL components like hash, search, or path for more flexible duplicate detection. Users can set the scope to monitor duplicates within the active window or across all browser windows. Convenient hotkeys such as Alt+Shift+W to close all duplicates and Alt+Shift+D to toggle auto-closing streamline tab management. This forked version also adds the Alt+Shift+D shortcut for toggling auto-close mode, enhancing usability for power users.

Exceptional extension, full of options. It can check the container of each tab, if wanted, so there's no risk of closing tabs with the same URL, but with different credentials. It can search for duplicates in different windows. It lists the duplicates in a pop-up dialogue, so individual tabs may be closed. It has an option to compare titles, instead of URL, which is not so useful (instead, it could compare both URL plus title for a match, skipping some Pages which use cookies, local storage and other data bases to manage states, without relying on URL...)
