Prevent
The Windows guard intercepts the close button, Alt + F4, and Ctrl + Shift + W. “No” is selected by default.
WINDOWS + GOOGLE CHROME
One click shouldn’t erase your entire workspace.
TabSure™ adds a confirmation before Chrome closes—and keeps local session snapshots ready if something still goes wrong.
Created by Vic D. Cabiles · Free experimental prototype

SESSION VAULTLast snapshot saved just now
Recover
The Chrome companion stores up to ten snapshots of open tabs and restores any snapshot in new windows.
Stay private
No account, analytics, advertising, or server. Session information stays in Chrome’s local storage on your device.
INSTALLATION
Install both protection layers
- Download and extract the installer package.
- Double-click Install TabSure.cmd. Close Guard installs, starts, and is added to Windows startup automatically.
- Chrome opens its Extensions page and Windows highlights the correct extension folder.
- Enable Developer mode, choose Load unpacked, and select the highlighted folder.
Why one approval remains: Chrome prevents Windows programs from silently installing extensions. After Chrome Web Store approval, this final step becomes one Add to Chrome click.
Please note: This is an unsigned experimental prototype. Windows may display a security warning. Test it first with nonessential tabs.
