This is a browser extension that pulls video files from RedTube pages and saves them as MP4. It hooks into the player to detect available quality options, handles HLS stream conversion in-browser, and drops files into a Downloads subfolder. You get three free downloads to test it, then it's paywalled. The use case is straightforward: you want offline copies of videos you can already watch in your browser session. It works across Chrome, Firefox, and most Chromium variants. The repo includes detailed troubleshooting for detection failures and quality picker issues, which suggests the extraction logic can be finicky depending on how RedTube serves the media on different pages.
