About No Jack Zone

NoJack Zone - Stop Keyboard Hijacking NoJack Zone prevents websites from hijacking your browser's keyboard shortcuts. This anti-jackware extension protects essential shortcuts like Ctrl+F, Alt+Left, and Ctrl+C from being overridden by sites. When a site attempts to hijack your shortcuts, NoJack Zone automatically re-jacks control back to you, ensuring your browser functions exactly as intended. Stop keyboard hijacking.

Intercepts keyboard events at the window level using high-priority capture phase 2. Overrides preventDefault and propagation methods when protected shortcuts are detected 3. Monitors website attempts to block browser functionality and automatically re-jacks control 4.
