Booking.com Email Extractor Extension

I need a Google Chrome browser extension that lets me, as a Booking.com host, view and copy the real e-mail address of every guest who submits a booking request. When I open the reservation, message thread or booking overview inside my host account, the extension should automatically detect any hidden address data, unmask it and display it in a small, clearly labelled field that I can copy with one click.

Please build the solution to run entirely inside the browser—no external servers—so it works as soon as I install the .crx or load the unpacked extension. A simple on/off toggle in the toolbar is enough for settings.

Deliverables:
• Production-ready Chrome extension (.crx or unpacked folder)
• Clean, well-commented source code
• Quick README explaining installation and use

I will test by installing the extension, navigating to several live booking requests and confirming that each guest’s address appears instantly and copies correctly.
