The Stream Detector is a Firefox addon designed to streamline the process of managing and downloading multimedia streams. This tool is particularly useful for users who frequently engage with playlists and subtitles from various streaming protocols like Apple HLS, Adobe HDS, MPEG-DASH, and Microsoft Smooth Streaming. With its intuitive interface, users can easily track URLs and download audio or video files directly from the browser. The addon allows for the customization of download commands, transforming URLs into formats compatible with popular tools like yt-dlp and FFmpeg, which enhances user experience and efficiency.

In addition to its tracking capabilities, The Stream Detector provides a simple way to copy URLs through its popup menu, accessed via a toolbar icon. Users can choose to copy URLs directly or configure them with essential headers such as User-Agent and Cookie for a seamless download experience. However, it's important to note that mainstream platforms like YouTube and Vimeo may not be compatible with this addon due to their proprietary technologies, making direct use of dedicated tools preferable for those services.
