aclap-dev/video-downloadhelper — reverse-engineered prompt

Build me a browser extension like Video DownloadHelper.

I want it to work in Firefox, Chrome, and Edge. When I open a web page with a video, the extension should notice it, show an active icon, and let me click a simple popup to see the videos it found. If there are different qualities or HLS streams, show them in a normal way so I can pick one and download it. Make the flow easy for regular users, with clear names, file sizes when possible, progress, success messages, and helpful errors when something cannot be downloaded.

If the browser cannot save or merge a stream by itself, add a simple companion app option or at least a clean setup path for it. Please don’t build anything for bypassing DRM or paid content, just normal downloadable media.

Use current browser extension docs if you need to, and include the basic icons, install instructions, and a short README.
