MV3's service worker can't touch the DOM directly, so the autofill logic lives entirely in content scripts, with the service worker handling storage sync and messaging between them. I'll build the extension with a content script that reliably detects and fills form fields, a popup for managing saved data, and a production build with obfuscation handled through the bundle step. 1) Should this target Edge alongside Chrome, or Chrome only? Cheers, Shayan

I build Chrome/Edge extensions in JavaScript and TypeScript, and delivered a Manifest V3 extension last month for automated CRM login autofill. Autofilling with reliability is about matching input fields across non-standard forms, so I’d use a smart selector approach, not just fixed field names. Build includes code obfuscation via a production script. You get a readable dev bundle, and a locked prod one. The code is split for easy future updates if you want to add new sites or logic. Is user-saved data stored locally (browser storage), or do you need a backend for profile sync? I can fit this in this week. Pradeep

I have experience developing web applications and browser-based functionality using JavaScript, TypeScript, HTML, and modern frontend architectures. I can implement the extension structure, content scripts, form detection logic, autofill workflow, storage handling, and prepare an optimized production build with source protection. I will ensure the extension works correctly across supported Chrome-based browsers and provide organized code that can be maintained or extended later. Can you provide examples of the target websites or form fields that the extension needs to support?
