I need a browser extension that can inspect specific pages, pull out the text, images and any data the user enters into forms, then immediately push that payload to the user’s account on our existing app. The same codebase should work in Chrome (Manifest V3) and Safari. Core flow • When a user visits one of the target domains, the extension detects the page, scoops up the requested elements (text nodes, image URLs/blob data, form field values) and displays a quick “Save” action in the toolbar or within the page. • On click, the data is serialized, authenticated with the user’s token (already available in local storage) and posted to the app. • The extension also prompts the user to take certain actions on that webpage. Deliverables 1. Production-ready .crx / .safariextz (or equivalent) packages 2. Full source code with clear comments 3. One-page test protocol proving that text, image and form capture all work on at least two sample sites per browser Acceptance criteria – Zero console errors and no content-security-policy violations on the monitored pages – Data reaches the endpoint in the agreed form – Extension installs and runs on the current public versions of Chrome and Safari without manual flag changes Please SHARE examples of similar extensions you have created, especially cross-browser, with a live link

Hi there, I’m Muhammad Awais and I can build a production-ready cross-browser extension that runs on Chrome (Manifest MV3) and Safari from a single codebase. It will detect visits to your target domains, collect text nodes, image URLs/blob data, and form values, and present a quick Save action in the toolbar or on the page. When the user clicks Save, the payload is serialized and posted to your app using the user token from local storage, with reliable error handling and secure transport. The same codebase will be packaged as Chrome .crx and Safari-compatible formats, with clear comments, CSP-conscious scripting, and straightforward installation steps. Deliverables include production-ready packages, full source with comments, and a one-page test protocol showing capture of text, images, and form data on at least two sites per browser. Acceptance criteria will be met with zero console errors, no CSP violations, and proper data delivery to your endpoint. I can share examples from similar cross-browser projects on request. Which target domains should the extension monitor? What is the exact payload format for text, images, and form data you want posted to your app? How should we handle authentication when the token is missing or expired? Do you require any in-page UI prompts or constraints on Save actions? Are there any security, privacy, or data-retention requirements we must follow for captured data? Best regards,

i can Hello there, I’ll deliver a production-ready cross-browser extension (Chrome MV3 + Safari) that inspects target pages, scoops text, image URLs/blob data, and form values, then instantly pushes a serialized payload to your app using the user token stored in localStorage. The same codebase will run on Chrome and Safari, with a unified build and clear separation between content scripts, background logic, and the UI. Deliverables include: production-ready .crx / .safariextz equivalents (or their modern equivalents), fully commented source code, and a one-page test protocol proving text, image, and form capture on two sample sites per browser. To ensure smooth integration, I’ll implement a stable Save action in the toolbar, CSP-safe data transfer, and a clean authentication header. Would you like me to start with two target domains for testing? Do you have a preferred data payload schema for the endpoint? Best regards,
