Close duplicate tab is a free Chrome extension developed by heppokofrontend. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory.

This extension is particularly useful for individuals who receive a large number of notifications from platforms such as GitHub, Redmine, and Backlog. Often, users tend to open these notifications in new tabs to read them later, resulting in an overwhelming number of tabs.

Close duplicate tab provides a solution to this problem by allowing users to organize their tabs instantly and reload the remaining tabs to keep them up-to-date.

With the recent update to version 1.0.3, the extension now supports English language and utilizes a dialog for all task buttons. Additionally, bugs related to the confirm dialog have been fixed.

Versionintroduced a new function called "Divide all tabs for each hostname," which groups tabs into the same window based on the number of tabs with the same hostname.

In version 1.0.1, a critical bug that prevented the loading of savedata was fixed.

Overall, Close duplicate tab is a stable release that offers a convenient solution for managing and organizing tabs in Chrome.
