關於此擴充套件
Secure your active Firefox session with style. Canvas Pattern Browser Lock by ABD overlays a full-screen, interactive HTML5 Canvas lock screen over web pages, blocking access until your private node pattern is drawn.
Running entirely locally within your browser (API-less), ABD's locker provides an air-gapped security layer for your open tabs.
Key Features:
Visual Pattern Security: Unlock using a complex drag-and-drop pattern across a 3x3 node grid, rendered directly on a high-performance HTML5 Canvas.
Zero-API Privacy: ABD's extension requires no external APIs, tracking, or backend servers. All configuration and state are stored locally within Firefox's secure browser.storage.
Dynamic Visuals: The lock screen features an animated particle background simulation and glowing neon path tracing at 60 FPS.
Live Configuration: Set your security pattern visually by drawing on a recorder inside the extension popup. Includes a security question recovery option.
Cross-Tab Synchronization: Locking or unlocking triggers an immediate state broadcast across all active browser tabs.

This Manifest V3 extension was optimized specifically for Firefox's advanced security sandbox. It uses pure HTML5 Canvas for UI rendering to achieve high performance on both desktop and mobile Firefox, while ensuring that the lock screen is impenetrable by the underlying webpage’s JavaScript. For developers porting MV2 extensions, note that this ABD implementation relies heavily on the browser namespace rather than chrome, and uses session-persistent MV3 listeners to maintain the isLocked state across browser restarts without a background page. Future ABD updates will focus on optimizing memory usage on low-power devices.
