Playlist Guru 제작자: Media.Dude

Playlist Guru turns Firefox into a real media player with two independent playlists — one for video, one for audio — that live entirely on your own device. Not only is it self contained but plays with other media players by our extraction tools.

🎬 Video Playlist

Add any video link manually, or right-click a video/link on any page →
"Add to Playlist"
Automatically detects HLS (.m3u8), DASH (.mpd), and FLV manifest links a page loads in the background — even when there's no visible <video> tag to right-click
Plays HLS, DASH, FLV, MPEG-TS, and every format your browser supports natively (mp4, webm, ogg, mov, and more)
Playback speed control, pinch-free zoom with click-drag panning, and an optional audio-boost/bass/treble enhancer
Drag-and-drop reordering, filtering, shuffle, and loop
Extract Audio: pull the audio track out of any direct video file and get a real MP3 — downloaded to your computer and added straight to your

🎵 Audio Playlist

Completely independent from the video side — keep music playing while you browse the video tab, or vice versa
Supports every audio codec your browser can decode (mp3, flac, aac, m4a, ogg/opus, wav) plus live HLS/DASH/FLV radio and internet streams
Full transport: seek bar, volume, speed control, shuffle, loop, prev/next, Export, anywhere

~Both Players~

Can export to a standard .m3u file (with titles intact) that opens straight into VLC, Winamp, foobar2000, and virtually any other media player — or a plain .txt list of URLs if that's what you need instead.
Built for real streaming sources Playlist Guru works great with direct-hosted files, Internet Archive, Icecast/Shoutcast internet radio, podcast enclosures, and your own hosted media. It does not, and cannot, bypass DRM or signed/session-locked URLs from platforms like YouTube, Spotify, or SoundCloud — those services
deliberately design their stream URLs to not work outside their own player,
and this extension respects that.
