Long description: HAR Debugger is a lightweight network recording extension for developers, QA engineers, and support teams. Instead of opening Chrome DevTools, users can start recording from the extension popup, reproduce a network issue, then stop and export a standard .har file. This major update improves both reliability and usability: popup-based controls, live recording status, onboarding guide, multilingual UI, background HAR generation, graceful response body collection, and optimized large-file export. Exported HAR files can be imported into Chrome DevTools Network panel and other HAR-compatible analysis tools. Common use cases: - Debug frontend API issues - Capture network evidence for bug reports - Support QA and customer troubleshooting - Record requests without asking users to open DevTools - Export shareable HAR files for HTTP/HTTPS analysis HAR Debugger only captures network events from the current tab after the user > explicitly clicks “Start recording”, and generates a HAR file locally after the > user clicks “Stop and export”. The extension does not upload HAR data, request > content, cookies, tokens, or browsing data to any remote server. All processing > happens locally in the user’s browser. Note: HAR files may contain URLs, headers, cookies, tokens, and response bodies. Share them carefully.
