Add‑Param από Bigdav

Add‑Param is a Firefox extension designed for security researchers, bug bounty hunters, and developers who need to test how web applications handle query parameters.

Features:
- Extracts parameters automatically from links, forms, URL fragments, and network requests (XHR/fetch).
- Allows adding custom (manual) parameters.
- Merges automatic and manual parameters, removes duplicates, and appends common values to each.
- Opens generated URLs in new tabs in batches of 20 for efficient testing.
- Provides a modern dark UI with a dedicated "Run Auto Extract" control.

The extension runs entirely locally, with no external requests or services.
