About this extension
Tab Lock is an advanced privacy and productivity extension designed to hide your active browsing sessions from prying eyes. Whether you're working on sensitive data, gift shopping, or just want to keep your desktop clean, Tab Lock gives you total control over your tab's visibility.

Key Features:
🎭 Google Disguise Mode: One-click transformation. Instantly mask any tab with a pixel-perfect Google Search replica. No password required—just click "Remove Lock" in the popup to return to your content.
🔒 Cryptographic Password Lock: Secure your tabs behind a full-screen vault. Uses industry-standard PBKDF2 hashing (75,000 iterations) to ensure your passwords are never stored in plain text.
🕵️ Metadata Masking: Automatically scrubs tab favicons and renames tab titles (e.g., "New Tab" or "Google") so your browser's tab bar looks innocent even when someone is standing right behind you.
☢️ Nuclear Failsafe: Our most aggressive security feature. If the extension is forcibly disabled or uninstalled, all protected tabs will immediately clear their content and close themselves to prevent any data leakage.
⌨️ Panic Shortcut: Press Ctrl+Alt+L (or your custom shortcut) to instantly trigger all locks and move your focus to a safe page.
📝 Private Vault Notes: Attach encrypted notes to your locked tabs that only reveal themselves once the correct password is entered.
📱 Firefox for Android Compatible: Full support for mobile browsing.
Tab Lock runs entirely offline. We never collect your data, see your passwords, or make any network requests. Your privacy is managed locally on your device.
