It provides a high-performance, premium environment to inspect the source code of any extension from the Chrome Web Store, Firefox Add-ons (AMO), Microsoft Edge Addons, and Opera—no manual downloads or local extraction required.

• One-Click Inspection: Open the source code of any extension directly from its store listing.
• Multi-Store Support: Seamlessly switch between Chrome, Firefox, Edge, and Opera extension analysis.
• Context Menu Integration: Right-click any link to a web store page to jump straight into the source.

🎨 PREMIUM DEVELOPER EXPERIENCE
