Linux Filesystem di Libor Benes (Dr. B)

Linux Filesystem brings a clean, high-contrast, searchable reference of the Linux Filesystem Hierarchy Standard (FHS) directly into your Firefox sidebar.

Instantly access clear explanations for every major directory (/, /etc, /var, /usr, /boot, /home, etc.) and key subdirectories — perfect for learning, troubleshooting, scripting, and daily Linux use.

Designed for Linux beginners, system administrators, DevOps engineers, security professionals, students, and power users who want fast access to the Linux directory structure without switching tabs or searching man pages.

🏛 About Linux Filesystem:
The Filesystem Hierarchy Standard (FHS) defines the standard directory layout used across virtually all Linux distributions. Remembering the purpose of each directory — especially under /etc, /usr, and /var — is essential for navigation, administration, security hardening, and troubleshooting.

This extension solves that by providing a well-organized, instantly searchable collection of all core FHS directories with plain-language explanations.

📐 Desktop Sidebar Design:
• Appears as a persistent, always-available sidebar in Firefox.
• Sticky Search Bar: Neon input field with real-time filtering as you type.
• Directory Cards: Clean, readable cards showing the path and its purpose.
• Subdirectory Sections: Important subdirs under /usr and /var displayed inline.
• High Contrast Neon Theme: Optimized for excellent readability in dark and bright environments.

⚙ How It Works — 100% Client-Side:
The extension runs entirely locally in your browser. No servers, no accounts, and no data collection of any kind. All directory information is stored in a static JavaScript array and loaded from the extension package. Nothing is ever sent over the network.

📊 What You See:
🔍 Live Filtering — Results update instantly as you type keywords like etc, log, boot, usr, or config.
✨ Clean & Bright — Deep dark background with vibrant cyan, yellow, green, and magenta accents.
📋 Excellent Readability — Spacious cards with clear descriptions optimized for sidebar use.
🌌 Neon Aesthetic — High-contrast design that looks great in any lighting.

🖥 Features:
🗂 Complete FHS Reference — All standard root directories plus the most important subdirectories under /usr and /var.
🔍 Instant Search — Filter across paths and descriptions in real time.
📋 Clear Explanations — Focused on real-world usage and purpose.
🗃 Well-Organized — Root-level cards with inline key subdirs for quick understanding.
🔒 100% Client-Side — No telemetry, no tracking, explicitly declared in manifest.json.

🎯 Perfect for:
• System administrators and power users.
• DevOps and SRE engineers managing servers and containers.
• Security professionals auditing and hardening systems.
• Linux newcomers learning the filesystem layout.
• Students and educators teaching Linux basics.
• Anyone who works in the terminal or manages Linux systems daily.
