Description

Chrome Extension Expert Needed – Fix 403/Blocked Requests While Manual Flow Works Description I have a Chrome Extension (Manifest V3) that automates actions on a web application. Current issue: * Manual browser flow works correctly. * Extension requests intermittently fail with 403 responses. * Response sometimes returns an HTML challenge page instead of expected JSON data. * Browser session is authenticated and cookies are present. * Need an expert to analyze request flow and identify why automated requests are being rejected while manual requests succeed. Scope: * Compare working manual requests vs extension-generated requests. * Analyze headers, cookies, session handling, request timing, and authentication context. * Review Manifest V3 service worker implementation. * Identify missing request attributes or browser context differences. * Implement a reliable fix and provide tested working solution. Required Skills: * Chrome Extension Development (Manifest V3) * JavaScript * Network Request Debugging * DevTools / HAR Analysis * Puppeteer (optional) * Authentication & Session Management * Browser Automation Please apply only if you have previously debugged situations where: * Manual browser actions work * Automated/extension requests fail * HTML challenge pages are returned instead of API JSON responses When applying, briefly explain a similar issue you have solved before.
