Prevent Chrome from closing without warning.
This extension opens a tab that can't be closed without your permission.
This prevents you from accidentally closing a multi-tab browsing session.
Clicking the icon toggles the lock tab on (red) and off (grey).
Click the red button on the Chrome Close Lock page to enable protection.
Chrome version 54 or higher is required.
NOTE: Something changed in newer versions of chrome that made it so you needed to interact with the page to actually make Chrome Close Lock active. We added the enable button as a temporary workaround. We are actively working to make it fully automatic again.
