Back to Close WE is a Firefox extension designed to enhance user experience by providing a simple solution for managing newly opened tabs. With this tool, users can effortlessly close tabs using the back button, offering a more intuitive way to navigate through their browsing sessions. This subscription-based add-on is particularly useful for those who frequently open multiple tabs and wish to streamline their workflow.

While Back to Close WE offers a straightforward functionality, it does come with certain limitations. Notably, it does not work on special pages such as 'about:' or on the Mozilla add-ons site. Additionally, users may notice a brief flash of an incorrect title on the window when using the extension, which could be a minor distraction during usage.
