KDP Watcher for Firefox geliştiren: Manish

This is a private productivity extension for KDP (Kindle Direct Publishing) authors to automate their royalty tracking.

The extension:
1. Only activates on kdp.amazon.com and kdpreports.amazon.com domains
2. Extracts page HTML and sends to user's own backend server
3. Requires user to configure their backend URL in the popup

This is not a public consumer extension - it's a tool for publishers managing their book portfolios.
