Tab Session Manager for Chrome, Firefox, and Edge will save/restore the state of your windows and tabs.
It happens, you are working between multiple tabs, and boom; you accidentally close them all out, potentially losing all that you were working on. Tab Session Manager is designed to save you from that frustration.
Tab Session Manager will save the current state of opened tabs, either manually or automatically, keeping your hard work available to you even if the tabs or windows are closed for whatever reason. It has many options to choose from, like user-defined keyboard shortcuts, session export for backup, session priority, and more.
Tab Session Manager is a useful extension/add-on for anyone who works with multiple tabs to manage and protect you from accidental loss of data contained on open tabs.
