Tab Privacy Lock од NOMUPAY SAS

Tab Privacy Lock helps you quickly protect open tabs when you step away from your computer, share your screen, or want to avoid accidental viewing.

The extension lets you lock the current tab with a local PIN. When a tab is locked, its content is replaced with a discreet local privacy screen. Entering the correct PIN restores the original page.

You can choose the interface language from the extension popup. The PIN and lock state are stored locally in your browser. Tab Privacy Lock does not collect personal data or send browsing information to external servers.

This extension is designed for quick visual privacy. It does not replace your operating system lock screen or provide encrypted session protection.
