I need a Google Chrome extension that speeds up the appointment-slot race on a specific government services site. The add-on should: • Auto-fill every required form field with user-saved data the instant the booking page loads • Watch the calendar in the background, refresh at a reasonable interval, and grab the first open slot that meets preset date or time rules • Alert the user the moment a slot is secured—or, if no slot is found yet, send a desktop or push notification as soon as one appears All logic must run client-side, respect the site’s existing captcha or token flow, and fall back gracefully if the page layout changes. I’ll need the unpacked source, a signed .crx ready for one-click installation, and a brief README that shows how to update selectors should the site’s HTML change. Keep the code clean, commented, and limited to standard Chrome APIs (no third-party automation services). Once I can install the extension, save my profile, walk away, and return to a confirmed booking, the job is complete.

Greetings, It sounds like you're looking for a reliable Chrome extension to help users quickly secure appointment slots on a government services site. The challenge lies in making sure the extension can handle form filling, background monitoring, and notifications, all while respecting the site's security measures. How to achieve this: - Develop a robust auto-fill system that uses user-saved data, ensuring it activates immediately when the booking page loads. - Implement a background script that refreshes the calendar at set intervals, capturing the first available slot based on user-defined criteria. - Create a notification system that alerts users when a slot is booked or when one becomes available. With my background in JavaScript, PHP, and web development, I can ensure clean, efficient code that adheres to Chrome’s standards. I can also provide a clear README for easy updates if the site changes.

Hi, I'd be happy to help develop your Chrome extension. I have experience building browser extensions, automating form workflows, and working with dynamic web pages using standard Chrome APIs. The extension will securely save user data locally, auto-fill the required fields, monitor appointment availability, and notify the user when a matching slot becomes available. The implementation will be designed to **work within the website's existing flow**, respecting any CAPTCHA or security verification required by the site. I'll also ensure the code is clean, well-commented, and easy to maintain, with a README explaining how to update selectors if the site's HTML changes. Could you please share the government website URL and any specific date/time rules you'd like the extension to follow? That will help me review the workflow and recommend the best implementation approach. Looking forward to discussing the project. Best regards, Naman

Hello, I can develop a clean Chrome extension that securely stores user profile data, automatically fills the required fields when the booking page loads, monitors appointment availability at a reasonable interval, and sends desktop notifications when a matching slot appears. To avoid violating the government website’s access rules or creating unfair automated bookings, the extension would not bypass captchas, tokens, rate limits, or complete the final reservation without user confirmation. When a suitable slot becomes available, it can open the relevant page, prefill the information, highlight the available appointment, and prompt the user to confirm immediately. The extension will use standard Chrome APIs only, include graceful handling for page-layout changes, configurable selectors, commented source code, and a README explaining installation and maintenance. I can provide the unpacked extension and guide you through packaging and distribution according to Chrome’s current extension policies.
