CookieScope nga Libor Benes

A powerful tool for debugging cookie issues, analyzing traffic and privacy, or learning about HTTP cookies, with a focus on simplicity, security, and user control. Designed for web developers, security researchers, and privacy enthusiasts to monitor and extract cookies in real-time over a sidebar.

Features:
• Two modes:
• Multi-Tab Capture,
• Active Tab Only.

• Copy Options:
• Individual cookies for one tab or the entire capture from all tabs.
• Cookie JSON only or full tab content (title, cookies, JSON).
• Buttons, CTRL+A, right-click, or mouse drag.

• Save Options:
• For a single tab (e.g., cookies_x_com_2025-09-01T03-47-00.json).
• For the entire capture for all open tabs (e.g., all_cookies_2025-09-01T03-47-00.json).

• Cookie Capture:
• Newest cookie at the top.
• Updates on tab activation, cookie changes, or page loads.

• Pause/Resume:
• Pause updates to prevent refreshes during analysis.
• Resume with queued updates.

• Privacy Support:
• Displays a message and “Open Privacy Settings” button if no cookies are found, linking to Mozilla’s Enhanced Tracking Protection guide.

• Performance:
• Uses a 2000ms debounce for updates (except tab activation) to balance responsiveness and resource usage.

Security and Privacy:
• Minimal Permissions.
• No Data Collection: Processes cookies locally without storage or transmission.
• Safe DOM.
• No Third-Party Libraries: Pure JavaScript, HTML, and CSS.
• Error Handling: Provides user-friendly alerts for clipboard or download failures.
• Manifest v2: Complies with Mozilla’s add-on standards.

• Limitations:
• Firefox’s Enhanced Tracking Protection may block cookies; disable over Settings or the provided link.
• Unsupported URLs: an error message displayed.
• Clipboard access may fail in rare cases; use Ctrl+C as a fallback.
• Multi-Tab mode may increase memory usage with many tabs.
