Close Other Tabs is a free Chrome add-on developed by zeckson. As the name suggests, it allows users to easily close all tabs except for the active one. This can be particularly useful for those who often have multiple tabs open and want to quickly declutter their browser.

With Close Other Tabs, you can either click on the extension icon directly or use the keyboard shortcut Alt+Shift+W to close all other tabs except for the active one and any pinned tabs. This functionality is especially handy for Chrome users who are using the Canary build of version 78, as it no longer provides the ability to close other tabs by default.

Overall, Close Other Tabs is a simple yet effective tool for managing your browser tabs. Whether you prefer using the mouse or keyboard shortcuts, this add-on offers a convenient way to quickly close unnecessary tabs and improve your browsing experience.
