Recently Closed is a minimalistic web extension designed for Firefox that enhances user experience by providing quick access to recently closed tabs and windows. It features a toolbar button that allows users to reopen the last closed tab or window effortlessly. Additionally, a right-click on the button reveals a list of all recently closed tabs and windows stored by Firefox, making it easier to manage browsing history without navigating through multiple menus.

This extension operates on a subscription-based model and allows users to modify browser preferences to increase the number of recently closed items that can be retrieved. However, it is important to note that the extension relies on Firefox's built-in session management, which limits the number of sessions to a maximum of 25, regardless of user-set preferences. This straightforward tool is ideal for users seeking a quick and efficient way to manage their browsing sessions.
