Whois & RDAP Domain Inspector for Thunderbird
Secure, precise, and automatic domain intelligence directly in your inbox.
The Whois & RDAP Domain Inspector is an essential tool for email security, enabling instant domain ownership analysis without leaving Thunderbird. Unlike basic lookup tools, this extension utilizes the official Mozilla Public Suffix List (PSL) to provide accurate domain identification, even for complex TLDs.
Why choose this extension?
When evaluating email threats, identifying the actual owner of a domain is crucial. Our extension goes beyond simple domain parsing by correctly identifying the registrable domain (eTLD+1), ensuring you get the most relevant registration data, every time.
Key Technical Capabilities
* Intelligent Domain Parsing: Robust extraction logic handles standard RFC 5322 From: headers, including display names, quoted parts, and address literals (IPv4/IPv6).
* PSL-Driven Accuracy: Uses a local, high-performance trie-based implementation of the Mozilla Public Suffix List to determine domain boundaries correctly.
* Configurable RDAP Services:
* User-Friendly View: Uses client.rdap.org for clean, human-readable HTML reports.
* Raw Data View: Offers direct integration with rdap.org for raw JSON access, perfect for security analysts and developers.
* Maintenance-Free: Automatically manages its own local cache of the Public Suffix List with daily background updates.
* Privacy-Focused: The extension performs no tracking. All processing happens locally, sending requests only to the selected RDAP service provider.
Perfect for:
* Email Security Analysts: Quickly assess suspicious senders.
* Developers & IT Pros: Verify domain configuration and ownership instantly.
* Power Users: Simplify domain lookups without manual copy-pasting.
Privacy & Reliability
Built with modern standards using ES Modules and clean, modular code. The extension is designed to be stable, lightweight, and respectful of your workflow.
