About this extension
Sandbox Workspace Sidebar is a powerful extension designed for your browser's sidebar, empowering your workflow and privacy through advanced session isolation.

🌟 CORE FEATURES:
• Auto-Sandboxing: Every time you add a new bookmark, the extension automatically generates a dedicated and isolated Container. Clicking the bookmark launches the URL in its own isolated environment with dedicated cookies and sessions.
• Conflict-Free Multi-Account Browsing: Easily save and open multiple bookmarks for the same website (e.g., Facebook, Google, Mail) to log into multiple accounts simultaneously without data overwrites.
• Intuitive Interface (Clean UI/UX): Bookmarks are organized in a clean 3-column grid layout within the sidebar. Supports custom grouping and smooth Drag & Drop for quick categorization.
• External Edit Window: Right-click any bookmark or group to open a separate popup for editing information with real-time sidebar synchronization.
• Master Password Lock: Secure your private bookmark collection with a master lock overlay. Your password is fully hashed locally using the robust PBKDF2 (SHA-256) algorithm.

🔒 PRIVACY ASSURANCE:
Your privacy is our top priority. All bookmarks, group structures, and hashed passwords are saved 100% locally on your device via secure local storage. This extension DOES NOT collect, track, or transmit any user data to external servers.
