Dario Locker: App & Tab Lock Firefox

Dario Locker: App & Tab Lock

Absolute defense for your privacy. Lock browser access with a Master Credential and use inactivity Auto-Lock to keep your tabs and data automatically shielded when you step away.

Features & Capabilities

Dario Locker is an advanced browser protection system, ideal for those who demand maximum privacy in the digital environment. Whether you share a computer at work, at home, or simply want an inflexible security layer when you step away, Dario Locker acts as a true defense hub, tactically and instantly preventing unauthorized access.

🌟 Main Features:

⏱️ Inactivity Auto-Lock (Idle Mode): No need to remember to lock it! The system features a high-precision hybrid engine that detects when you stop using the browser. Choose a timer (from 1 to 60 minutes) and it will arm the lock automatically once the time is reached.

🔒 Instant Lock & Security Curtain: Protect your browsing with one click on the "Block" button. The lock acts even before pages render on the screen, hiding your active tabs immediately.

🔑 Flexible Master Credential: Choose your security level with 4, 6, or 8-digit keys. Includes an anti-autofill tactical panel (prevents browser password managers from interfering) and a dynamic visibility toggle button.

🛡️ Core Shield (Zero-Trust): An aggressive defense system that isolates access to vital URLs (like the settings tab and extension store). This prevents intruders from trying to bypass, disable, or uninstall the lock while the system is armed.

📊 Internal Monitoring (Console Log): Know what happens when you aren't looking. A built-in terminal records and displays precise inactivity logs (e.g., "Returned to browser after 2 min away") and the exact times the defense was armed or disarmed.

🌍 Bilingual Support: Switch seamlessly between English and Portuguese directly from the interface.

📧 Secure Recovery Protocol (Optional): Forgot your credential? Register a security e-mail to request a temporary numeric PIN and restore access to your browser in emergency situations.

🌑 Tactical & Premium Design: A clean interface divided by quick-config tabs, built entirely on a professional Dark Mode theme that is easy on the eyes.

🕵️ Absolute Privacy: All processing is done locally. We do not track your tabs, history, or activity. The only external communication occurs exclusively to send the recovery PIN to your own e-mail.

Is Dario Locker: App & Tab Lock Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
