Your extension already works, so the real issue is the scraping logic no longer reliably pulling data from the target site — usually that means the site's DOM changed, or content now renders dynamically after load. I'd start by auditing your content script against the live DOM, then rebuild the extraction with resilient selectors instead of brittle nested paths, and add a MutationObserver so data that loads lazily (infinite scroll, async fetches, SPA re-renders) gets captured instead of being missed on first paint. For anything the DOM hides, I'll check the site's own network/XHR responses and pull structured JSON directly, which is far more stable than parsing markup. I'll keep everything MV3-compliant — content script for extraction, service worker for orchestration and messaging — and wire in retry/error handling so a single failed node doesn't kill the whole run. TypeScript throughout, tested against real pages before handoff via Git. I've done plenty of scraping and Chrome extension work across 249+ projects. One question that changes the approach: is the target data server-rendered in the HTML, or does it appear only after JavaScript/API calls fire? That decides whether we scrape the DOM or tap the underlying requests. Muhammad Saad

Hi, I understand you need a stable scraping logic that works consistently with the site's DOM changes, not just a quick fix. I recently rebuilt a Chrome extension's scraping layer after a site update broke the old selectors, using Manifest V3 and TypeScript to make the selectors more resilient. I'd approach this using a modular content script with dynamic selectors, keeping the background worker minimal for permissions. The biggest improvement will come from isolating the scraping logic so changes don't break the whole extension. I'll test each selector fix against the target site before committing changes, and keep the original functionality intact. This should make the extension more reliable for your users. If you want to move forward, I can start right now. Thanks, Denis

Hi. To fix this Chrome Extension scraper, I’ll trace the content script flow, inspect the target DOM behavior, and update the extraction logic for Manifest V3 reliability. I’ll harden selectors, event timing, and async handling so the extension keeps working even when the page structure shifts. I’ll also review the background service worker and messaging path to make sure scraped data moves cleanly into the UI or API layer. As a Senior React Developer, I have mastered JavaScript, TypeScript, React.js, Chrome Extension Development, and have strong experience in Manifest V3 extensions, DOM manipulation, and web scraping projects. I am sure I can deliver high-quality results within a short timeline for this scoped fix. Let’s get in touch and discuss more. Thanks.

Hi, Ah yes, the classic story: "Everything works perfectly... except the part that actually does the work." ? I've worked with React, Chrome Extensions, Manifest V3, web scraping, and browser automation, so updating the scraping logic should be pretty straightforward. Most of the time, these issues come down to one of a few usual suspects: * The target website changed its DOM structure. * Timing problems (React and JavaScript-heavy pages love to play hide-and-seek). * Manifest V3 permission/service worker quirks. * Content scripts firing before the page is fully loaded. * Selectors that were written during happier times. For a $25 project, my plan would be simple: 1. Review the existing extension architecture. 2. Debug the current scraping flow. 3. Update the selectors and extraction logic. 4. Verify compatibility with Manifest V3. 5. Test across multiple page loads and edge cases. 6. Deliver the fix with a brief explanation of what changed. And don't worry—I won't "fix" it by adding a `setTimeout(10000)` and calling it enterprise-grade software. ? Send me the repository (or ZIP), the target website, and a quick description of what's failing, and I'll take a look. Best, Rawan

I’ve built and debugged Chrome Extensions with Manifest V3, React, and content scripts before—so this is straightforward. I’ll audit the existing scraper logic, identify the brittle selectors, then rewrite the DOM traversal in TypeScript to target the site’s current structure. I’ll handle extraction, data normalization, and push via REST API, ensuring parity with the extension’s background worker and service calls. Git versioning covers the rollout; validation runs in CI before publishing to Chrome Web Store. I can start immediately. Thanks, Andrii.

A SCRAPER THAT BREAKS ON ONE DOM CHANGE ISN'T FIXED, IT'S JUST WORKING TODAY. Hello, my name is Jonas, full stack developer. Finding exactly where the current selectors or logic fall out of sync with the target site, that's the real fix here, not just patching symptoms. So the first step is going through the existing content script and background service worker to see where the extraction actually breaks. The scraping logic gets rebuilt around more reliable selectors, so small site changes don't break it again right away. Manifest V3's service worker limits get handled properly, so the extension stays stable instead of silently failing in the background. The React side stays untouched where it already works, so this fix doesn't turn into a rebuild. I've debugged Chrome extensions and scraping logic before, tracing failures back to DOM or manifest issues. Everything gets tested live against the target site before calling it done. Quick one, can you share the current extension code or repo, so I can see exactly where the scraping breaks? You end up with a scraper that keeps working, not one that needs fixing again next week. Let me know if this sounds right, ready to start.

Hi, I can debug and modernize the Chrome Extension’s scraping pipeline so it pulls clean data reliably from the target site. I rebuilt a React-based scraper last month that handles dynamic DOM changes by isolating content scripts from the background worker using Manifest V3 messaging. I’d approach this by moving the scraping logic into a content script sandboxed behind a declarative net request rule, then funneling the results to the background service worker via chrome.runtime.sendMessage. The biggest improvement will come from adding mutation observers to catch late-rendered elements without breaking the extension’s CSP. I’ll keep every change small and test it against the live site so existing pages stay functional. No surprises—you’ll see each patch before it ships. This keeps scrapes consistent and avoids extension reloads that frustrate users. If the patch looks good, I can push an update straight to the store and keep the repo clean for future tweaks. Thanks, Lazar.
