NewTabBeforeClose is a Chrome extension developed by DebuggerX that enhances the browsing experience by automatically opening a new tab instead of closing the browser when the last tab is closed. This behavior is similar to the "世界之窗" browser.

With NewTabBeforeClose, you no longer have to worry about accidentally closing the browser when you intended to close the last tab. Instead, a new tab will be opened, allowing you to continue browsing seamlessly.

This free Chrome extension is a valuable tool for users who frequently work with multiple tabs and want to avoid the inconvenience of accidentally closing the browser. By simulating the behavior of the popular "世界之窗" browser, NewTabBeforeClose provides a familiar and intuitive experience.
