Extension Metadata

About this extension
about: System Configuration brings a complete, high-contrast searchable configuration directory and reference index for advanced configurations directly into your desktop sidebar for Firefox browser. (Note: This add-on is not official Mozilla software.) With real-time filtering, it instantly maps out the internal ecosystem, bringing deep runtime diagnostics, network tracking logs, and performance modules together in one interface.

Designed for power users, extension developers, security auditors, and browser enthusiasts who need quick, authoritative access to native internal engine endpoints without leaving their active tab workflow.

🏛 About Internal Browser Diagnostics:
When diagnosing browser anomalies or auditing active security settings, manually typing out obscure about: links is highly inefficient. To manage a responsive browser, you need systematic visibility paired with descriptive classification.

Understanding the technical footprint of internal links is fundamental to:
• System tuning — uncovering hidden parameters to optimize resource consumption.
• Troubleshooting workflows — tracking down crashing tabs or isolated network pipeline issues.
• Forensic visibility — checking active enterprise policies, tracking blocks, and certificate trails.

📐Desktop Sidebar Design:
about: System Configuration is a persistent sidebar panel — always available alongside any tab you are working in.

• Sticky Search Bar: A high-visibility neon input box with automatic focus for real-time text filtering.
• Category Headers: Color-coded neon title banners grouping targets logically across 5 separate domains.
• Command Cards: Compact metadata boxes featuring monospace URLs and clean, short descriptions.
• Clipboard Action: Integrated inline copy controls to duplicate paths instantly without selecting text.

⚙ How It Works — 100% Client-Side:
The extension runs entirely within your browser. No servers, no accounts, no data collection of any kind. All content is static JavaScript loaded from the local extension package. Nothing is ever sent anywhere. Closing the sidebar resets nothing — the static reference matrix remains immediately available upon reopening.

📊 What You See:
🔲 Focus state: The search input transitions to a sharp pink glow indicating active keyboard capture.
🔄 Real-time update: Irrelevant entries immediately drop from the sidebar viewport as you type letters.
✨ Copied state: The action button dynamically changes text and color to confirm clipboard execution.
🌌 High contrast: Deep space backgrounds combined with neon accents to prevent visual fatigue.

🖥 Features:
🗺 Map the Ecosystem — Instantly visualize the hidden diagnostic and architectural pages powering your browser environment.
🔍 Instant Filter — Type any letter or concept to automatically hide mismatching rows across all categories simultaneously.
📋 One-Touch Clipboard — Click the dedicated button on any card to instantly copy the exact URL path.
🗂 Clean Categorization — 44 verified system endpoints organized neatly into distinct system rows.
🔒 100% Client-Side — No data collection, no telemetry, no tracking. Explicitly declared in manifest.json.

🎯 Perfect for:
• Penetration Testers who need to audit advanced security settings, active enterprise policies, and connection overrides during browser assessments.
• Threat Researchers analyzing live tracking layers, certificate details, and automated phishing protection lists directly from the engine source.
• Forensic Analysts establishing a clean record of internal configurations, device debugging hooks, and memory allocation trails.
• Power Users & Developers tuning performance trace metrics, investigating background service worker behavior, and hacking hidden browser variables.

🔒 Security-First Architecture:
✅ No Data Collection — Explicitly declared in manifest.json.
✅ No Telemetry — No analytics, no external pings, and no network requests of any kind are generated by the extension.
✅ No Risky Coding Features — Pure, statically analyzed code that satisfies strict native web security policies and review criteria.
✅ Input Validation — Filter strings are cleanly sanitized, trimmed, and normalized to lower-case values during runtime array scans.
✅ No Icons — Zero binary dependencies or external tracking assets are included inside the extension package.
