Close Duplicate Tabs is a free Chrome extension developed by Robert Graham. As its name suggests, this simple yet effective add-on is designed to streamline your browsing experience by closing duplicate tabs with just a single click.

With Close Duplicate Tabs, you no longer have to spend time manually closing multiple instances of the same website. Whether you have accidentally opened duplicate tabs or have accumulated several tabs over time, this extension provides a convenient solution.

The interface of Close Duplicate Tabs features a prominent red button that allows you to instantly remove all duplicated tabs in one go. This can be particularly useful if you tend to have multiple tabs open for job applications, tutorials, documentation, or any other purpose. By eliminating unnecessary duplicates, you can declutter your browser and focus on the essential tabs.

It's worth noting that Close Duplicate Tabs identifies duplicates based on the hostname of the URL object in JavaScript. This means that if you have tabs with slightly different URLs but from the same website, the extension will consolidate them into a single tab. However, if you have tabs from different subdomains or different websites altogether, they will be treated as separate instances.

Overall, Close Duplicate Tabs is a handy Chrome extension that simplifies your browsing experience by efficiently managing duplicate tabs. With its intuitive interface and straightforward functionality, this add-on can save you time and help you maintain a more organized browser window.
