Browser Extension/ Web Data Collector for Chrome Safari

@AwaisChaudhry

Hi there, I understand you want a cross-browser extension for Chrome (Manifest MV3) and Safari that visits your target pages, pulls text, image URLs/blob data, and form field values, then sends a serialized payload to your app using the user token stored locally. I’ll implement a single codebase that detects the domain, captures the requested data on page load or navigation, surfaces a quick Save action in the toolbar or on the page, and posts the data securely to your endpoint. It will also prompt users to take actions on the page. Deliverables include production-ready packages (.crx / .safariextz or equivalents), fully commented source, and a one-page test protocol showing text, image, and form capture on at least two sites per browser. I’ll ensure zero console errors and no content-security-policy violations, and smooth install on current Chrome and Safari versions. I can share examples of similar cross-browser extensions on request. Which domains should trigger the extension, and how will you supply the list or pattern? Should we capture text, image URLs, blob data, and form values while skipping sensitive fields (passwords, payment fields)? How will we identify them? What is the exact payload schema and endpoint (URL, method, headers) for the data posted? Any required fields beyond text, images, and form values? What are the token handling details (token name in local storage, expiration, refresh), and how should authentication be enforced for the POST? Do you have

I can build a cross-browser browser extension using a single, clean codebase that works on Chrome (Manifest V3) and Safari, capturing page text, images, and form data and securely posting it to your existing app. The extension will detect target domains, surface a clear in-page or toolbar “Save” action, serialize the data with the user’s stored token, and prompt users for required on-page actions. I’ll deliver production-ready packages, well-documented source code, and a concise test protocol verifying capture across multiple sites with zero console or CSP issues. I’ve built data-capture and cross-browser extensions before and can share relevant examples upon request.

Hello, I can develop a cross-browser extension for Chrome and Safari to capture text, images, and form data from specified pages and push this data to your app. The extension will recognize target domains, gather the required elements, and offer a "Save" action. When clicked, it will serialize the data and authenticate using the user's token, ensuring seamless data transfer to your app. I will deliver production-ready packages (.crx and .safariextz), complete with well-documented source code. I'll also provide a test protocol to demonstrate successful data capture across sample sites. The extension will be optimized to avoid console errors and content-security-policy violations, ensuring smooth operation on the latest browser versions without needing flag changes. Could you specify any preferred frameworks or libraries for the extension? Also, do you anticipate any specific challenges with form data capture that I should be aware of? Looking forward to showcasing my expertise in creating robust, cross-browser solutions tailored to your needs. Thanks and best regards, Kamran

As an experienced web developer with over 8 years in the field, I have the expertise you need to create this browser extension that can seamlessly operate across Chrome and Safari. My past projects involve complex web operations like the one you've outlined and my profile speaks volumes of my competency and reliability. Mastery in JSON, web development, and web scraping ensures I'm capable of delivering your requirements flawlessly. Regarding your project specifics, I have successfully created similar extensions before, ensuring cross-browser compatibility and high-performance for my clients. One such extension is a data collector that 'scrapes' web pages for specific information, authenticates it securely, and sends it to be processed at a central location. This process mirrors what you require for your project's core flow. As evidenced by zero console errors, no content security policy violations on monitored pages, I am fully competent in handling these delicate aspects.

@WebColorIn

Hi, I'll build a Manifest V3 extension for Chrome and a Safari Web Extension from a single codebase using a cross-browser framework. The core will be a content script that uses the MutationObserver API to detect and serialize text nodes, image data, and form inputs, then securely POST the payload using the auth token from local storage. 1. Can you share the API endpoint spec and the two sample domains for testing? 2. What specific user actions should the extension prompt for on the webpage? Thanks, Satya - 15+ Years in Web Development

@DeveloperStation

Hi, We’ve developed multiple Chrome extensions that extract data from web pages and send it to a backend server. One of our extensions, called WebScraper, allows users to log in and scrape data from Amazon, eBay, and other sites, with the option to schedule automatic scraping. We also built a similar extension for a client that extracts data from LinkedIn and sends it to a third-party API. For your project, we can use a combination of content scripts and background scripts to extract data from the page and send it to the server. We can also implement a mechanism to schedule background tasks for regular data extraction. Let’s schedule a 10-minute introductory call to discuss your project in more detail and see if I’m the right fit. I’m available at any time that works for you. I’m eager to learn more about your exciting project. Best regards, Adil

Hi I can build a cross-browser extension (Chrome Manifest V3 + Safari Web Extension) that detects target domains, extracts DOM text, image URLs/blob data, and form-field values, then posts a signed payload to your existing API. The key technical challenge is reliable capture under strict CSP/permissions while keeping zero console errors across two very different extension runtimes. I solve this with a content-script + service-worker architecture, minimal host permissions, safe DOM traversal, optional blob fetching via background, and strict message passing. Auth will use the user token from extension storage (not page localStorage), with secure request signing, refresh handling, and hardened CORS/error retries. The “Save” UI can be toolbar-driven plus an in-page prompt overlay, injected only on whitelisted domains to avoid policy violations. I’ll deliver production packaging for both browsers, plus a repeatable test protocol and payload validation against your endpoint schema. If you want, I can share relevant code samples/screenshots of prior extension patterns (MV3 + Web Extension) privately. Thanks, Hercules
