NetSet for VirtualBox Autor: Libor Benes (Dr. B)

NetSet for VirtualBox brings a clean, high-contrast, searchable reference of Oracle VirtualBox networking modes directly into your Firefox sidebar.

Instantly access clear explanations for every network type (NAT, NAT Network, Bridged, Host-Only, and Internal networks) and key configuration properties — perfect for learning, troubleshooting, labs, and daily virtualization use.

Designed for virtualization beginners, system administrators, DevOps engineers, security professionals, students, and power users who want fast access to VirtualBox network structures without switching tabs or digging through official manuals.

🌐 About NetSet for VirtualBox:
Oracle VirtualBox provides multiple distinct networking modes to connect virtual machines to each other, the host, and the internet. Remembering the nuances, security implications, and isolation rules of each mode — and exactly how they impact host, virtual machine, and Internet connectivity — is essential for lab setup, administration, and troubleshooting.

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

📐 Desktop Sidebar Design:
• Persistent Sidebar: Appears as a persistent, always-available sidebar in Firefox.
• Sticky Search Bar: Neon input field with real-time filtering as you type.
• Network Cards: Clean, readable cards showing the network mode and its core rules.
• Capability Breakdown: Visual indicators for Host, VM, and Internet connectivity.
• 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 networking mode 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 nat, bridged, host, or isolation.
• 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 Network Reference: All standard VirtualBox networking modes plus critical configuration use cases.
• Instant Search: Filter across modes, use-cases, and descriptions in real time.
• Clear Explanations: Focused on real-world architecture, isolation levels, and routing rules.
• Connectivity Matrix: Quick visual reference of what each mode can and cannot talk to.
• 100% Client-Side: No telemetry, no tracking, explicitly declared in manifest.json.

🎯 Perfect for:
• System administrators configuring complex virtual topologies.
• DevOps and SRE engineers staging local multi-VM environments.
• Security professionals building isolated malware analysis or penetration testing labs.
• Virtualization newcomers learning hypervisor networking basics.
• Students and educators teaching network administration.
• Anyone who builds, tests, or manages VirtualBox virtual machines daily.

🔒 Security-First Architecture:
• No Data Collection: Explicitly declared in manifest.json.
• No Telemetry: Zero network requests or external connections.
• No Risky Code: Safe DOM methods only, no eval() or innerHTML.
• Minimal Permissions: Only clipboardWrite (if you enable mode name copying).
• Flat & Auditable Structure: Simple, transparent codebase.
