Overview
sUndoClose is a fork of the popular "Simple Undo Close" extension that makes it easy to restore recently closed tabs and windows. We've all accidentally closed an important tab or window—this extension ensures you can get it back with just one click or keyboard shortcut.
The extension maintains a session history of your closed tabs and windows, displaying them in a clean popup interface with favicons for easy identification. You can restore individual tabs or entire windows, and the extension supports multi-language localization.
With keyboard shortcut support (Alt+Z by default, MacCtrl+Z on Mac), recovering closed tabs is faster than ever. The extension is lightweight, fast, and designed to stay out of your way until you need it.
