✨ Key Features:
🛡️ Reliable Close Protection: The core feature — prevent accidental tab closures. DefendTab intercepts closing attempts and asks for your confirmation.
🔒 Smart Tab Lock: Activate the global lock mode to protect all your open tabs with a single switch.
✅ Exception List: Add sites that don't need protection to the allowlist. Perfect for temporary pages you open and close frequently.

🌐 Works Everywhere: Protection is active on any website, from web apps and documents to admin panels and online games.
🌙 Light & Dark Mode Support: The extension's interface adapts to your system's theme.
⚙️ Simple Controls: An intuitive popup menu lets you manage all features with a single click.
🚀 How It Works (Usage)
1. Install the extension.
2. Open any web page.
3. IMPORTANT: Click anywhere on the page once. This is a browser security requirement to activate the protection.
4. Try to close the tab by pressing `Ctrl+W` (or `Cmd+W` on Mac). You will see a confirmation dialog.
5. Click the extension icon in your toolbar to open the menu and configure exceptions or other settings.
🏆 The DefendTab Advantage
👉 Your Digital Safety Net: Think of DefendTab as the ultimate safety net for your browser. It acts as a reliable guardian for your online documents, filled forms, and critical work sessions, ensuring you never lose progress by mistake.
👉 Intelligent Navigation Detection: DefendTab is smart. It understands the difference between an intentional click on a link and an accidental command to close a tab. This means you can browse freely and seamlessly without interruptions, and the protection only kicks in when you truly need it.
👉 Total Control at Your Fingertips: You are in command. Use the master switch to toggle all features on or off. Use a convenient hotkey (`Alt+W` by default) to add or remove sites from your exception list on the fly. DefendTab adapts to your workflow, not the other way around.
👉 Lightweight & Secure by Design: Built on the modern Manifest V3 platform, DefendTab is optimized for performance and security. It's incredibly lightweight and won't slow down your browser, all while keeping your settings stored safely and locally on your machine.
🎯 Who is DefendTab for?

👤 Students & Researchers: Save tabs with important articles, sources, and online courses. Don't lose hours of research from one wrong move.
👤 Content Managers & Writers: Safeguard tabs with your articles, blog posts, or documents in online editors. Focus on creating, not on saving tabs.

🛡️ Privacy & Security — Our Top Priority
We built DefendTab with a deep respect for your privacy.
🔒 Zero Data Collection: The extension does not collect, read, or transmit your browsing history, page content, or any other personal information.
🔒 Everything Stays Local: Your settings (like the exception list) are securely stored only on your computer using the browser's native storage APIs. No data is ever sent to external servers.
🔒 Transparent Permissions: DefendTab only requests the permissions absolutely necessary for it to function—to protect your tabs on any site. We've explained each permission in detail in our Privacy Policy.
💬 Frequently Asked Questions (FAQ)
1. How does the protection work?
The extension uses the standard browser `beforeunload` API to intercept the tab closing event and show you a confirmation dialog. This is the most reliable method.
2. Will this extension slow down my browser?
No. DefendTab is extremely lightweight and optimized for minimal resource consumption. It is built on the modern Manifest V3 for maximum security and performance.
3. Why does the extension need access to all sites?
This is necessary so the protection works on any tab you might accidentally close. The extension does not analyze the content of the pages; it only reacts to the closing event. This is explained in detail in our Privacy Policy.
4. Can I disable protection for certain sites?
Yes! That's exactly what the VIP "Exception List" feature is for.
