Web Developer Tools Lite is a clean, lightweight, and privacy-focused extension designed for developers, designers, and web creators who need essential page inspection tools without the bloat. Built natively for Firefox (Manifest V3), it runs instantly without lagging your browser or consuming heavy system resources.

Whether you are debugging a quick layout issue, analyzing structural elements, or conducting a routine web audit, this extension provides an organized dashboard to streamline your daily workflow.

Key Features:

• One-Click Element Inspector: Quickly outline and analyze DOM elements, margins, padding, and structural tags directly on any live webpage.
• Storage & Session Overview: Easily view local storage, session storage, and active cookie keys in a clean, readable grid layout without opening the heavy built-in DevTools.
• Metadata & Structure Checker: Instantly verify page titles, meta descriptions, and header hierarchies (H1-H6) to ensure your document structure is perfectly optimized.
• Lightweight Design: No external scripts, no background tracking, and absolutely zero impact on browser performance.

Why Choose the "Lite" Version?

Unlike heavy development suites that require steep learning curves and slow down your browsing experience, Web Developer Tools Lite focuses strictly on core functionalities. It runs 100% locally on your machine, meaning your source code, data, and browsing history are never transmitted or shared.

Keep your workspace clean, your browser fast, and your development process efficient.



Built with privacy in mind. Completely free of tracking and remote script execution.
