domain-harvester is a lightweight, high-performance Firefox extension specifically designed for Bug Bounty Hunters and Penetration Testers. It streamlines the reconnaissance phase by automatically extracting, filtering, and organizing domain names and subdomains from any web page you visit.

• Instant Extraction: Harvest all Domains and Subdomains visible on the current page with a single click.
• Deep Extraction: Automatically harvests Domains and Subdomains directly from HTML and JavaScript pages.
• Auto-Filtering: Automatically removes duplicates and cleans the list for a noise-free output.
• Recon-Ready Export: Export your gathered domains directly to a .txt file, ready to be piped into tools like httpx, subfinder, or nuclei.
• Lightweight & Fast: Optimized to run smoothly without affecting browser performance.
• Privacy Focused: Works entirely on the client side; no data is sent to external servers.
