Duplicate Tab is a Chrome extension developed by zertosh that allows users to easily duplicate the current tab. With just a click of the "Duplicate tab" icon in the Google Chrome toolbar, users can instantly create a duplicate of the current tab they are on.

In addition to the toolbar icon, users can also set a keyboard shortcut for duplicating tabs. This can be done by navigating to "Window" -> "Extensions" -> "Keyboard shortcuts" and assigning a shortcut for "Duplicate tab".

One of the notable advantages of Duplicate Tab is its minimal resource consumption. It runs as an event page rather than a background page, which means there is no persistent process running in the background. Furthermore, the extension does not collect any analytics, ensuring user privacy.

If you find yourself frequently needing to duplicate tabs in Chrome, Duplicate Tab is a simple and efficient solution that can greatly enhance your browsing experience.
