About Don't Close

Ever lost unsaved work because Chrome decided to restart for an update? Don't Close fixes that. It quietly injects a lightweight guard into one of your open tabs. When Chrome tries to shut down, you'll get a "Leave site?" prompt — giving you time to save your work before anything closes. No extra tabs. No clutter. Just a simple toggle in the toolbar to turn protection on or off. Permissions: Don't Close needs access to your tabs in order to prevent them from closing. It doesn't read, collect, or transmit any data.
