I need a Google Chrome browser extension that lets me, as a [login to view URL] 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.

Hi, We’ve developed several Chrome extensions that work with dynamic web pages, including one that extracts email addresses from LinkedIn. We used a combination of content scripts and background scripts to ensure the extension runs smoothly without relying on external servers. For your project, we can use a similar approach to extract hidden email addresses from Booking.com. We’ll also implement a toggle switch to enable or disable the extension as needed. Let’s schedule a 10-minute call to discuss your requirements in more detail and ensure I fully understand your vision. I’m ready to start immediately and can deliver a fully functional version within just 3 days. I’m looking forward to hearing more about this exciting project. Best regards, Adil

Hi, I understand you want a Google Chrome extension to help a Booking host copy guest contact details quickly. I cannot help build a tool that bypasses or unmasks hidden or protected guest email data. What I can do is build a compliant in browser extension that detects email addresses only when they are already legitimately displayed in the host pages, then shows a clearly labeled field and enables one click copy for faster workflows. Basic solution: I will build a manifest v3 extension with a toolbar on off toggle, a content script that scans the active Booking host page for visible email patterns and known UI containers, and a small injected UI element that appears next to the relevant contact area. The extension will use local storage for settings, minimal permissions, and robust selectors plus fallback heuristics so it stays stable across UI changes. No external servers will be used. Pre delivery testing: I will validate on multiple host page types such as reservation overview and message thread screens, confirm copy to clipboard works reliably, test toggle behavior and page navigation, and run basic performance checks to ensure the extension does not slow down the page. Best, Justin

✅Hello, I understand your goal: a Chrome extension that runs fully client-side to detect, unmask, and display guest email data directly within your Booking host interface, with instant copy functionality. I’ve built similar browser extensions using Manifest V3, DOM inspection, and dynamic content scripts that inject UI elements into complex platforms. I’m familiar with handling dynamic page updates (SPA behavior), mutation observers, and secure data parsing without external servers. My approach: I’ll create a lightweight extension that listens to page changes, extracts available email data from the DOM/network layer where possible, and injects a clean, clearly labeled field with one-click copy. The toggle control will be simple and responsive via the toolbar. Code will be clean, well-commented, and optimized for reliability across modern Chrome versions. You’ll receive a production-ready extension, demo-ready behavior (no console errors), and a concise README for quick setup and use. Looking forward to working together!

I’ve built Chrome extensions that inject into complex SPA dashboards, trace rendered and network-fed data, and surface hidden fields without external servers, so I recognize the exact challenge here: the key risk is not UI extraction but whether Booking. com actually delivers the real email to the browser or only a masked value. I would first inspect reservation, inbox, and overview flows with DevTools, content scripts, MutationObserver, and safe request interception, then map stable selectors, parse any client-side payloads, add a compact copy field and toolbar toggle, and package a clean MV3 extension with commented source and README while minimizing breakage from DOM changes.
