Fast Duplicate Tab Closer is a free Chrome extension developed by ChatGPT Persona Extension. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory.

The main purpose of this extension is to prevent duplicate websites from opening by focusing on already opened tabs. When you open a tab with a website that has already been opened, the extension automatically closes the new tab and brings focus to the existing tab.

This extension offers several benefits. Firstly, it saves you time by preventing the need to wait for a duplicate website to load. Secondly, it ensures that you do not have multiple tabs open for the same website, making it easier to navigate through your tabs. Additionally, by avoiding duplicate tabs, your laptop's memory is not wasted on keeping redundant tabs open.

The Fast Duplicate Tab Closer extension has also received updates to enhance its functionality. The latest version, v0.0.8, has decreased the loading time for just opened duplicated pages, although this feature is currently only available for Chrome Beta. Other updates include changes to the extension's name and description, the addition of an option to move the old tab to a new position, and the ability to ignore hashes in URLs and change the hash on the old tab if a new page with a different hash is opened.

Overall, Fast Duplicate Tab Closer is a useful Chrome extension that helps streamline your browsing experience by preventing duplicate tabs and optimizing tab management.
