▶ Local Media Player+ — a full-featured media player for Firefox

Local Media Player+ brings local video, music, subtitles, IPTV, internet radio, Picture-in-Picture, an equalizer, clip recording, saved playlists, and timestamped notes together in one modern interface.

Open individual files, entire folders, and streaming playlists. Use the player in a browser tab, a standalone window, or the Firefox sidebar. Resume playback from where you stopped and manage your media collection without leaving the browser.

🔒 Your files stay on your device

Local Media Player+ plays local audio and video files directly from your device.

During normal local playback, your media files do not need to be uploaded to cloud storage or transferred to a remote server.

The player is suitable for:

— personal video and music libraries;
— movies and series;
— lectures and study materials;
— podcasts and audiobooks;
— language-learning content;
— work and meeting recordings.

An internet connection is used only for features that require it, including IPTV streams, internet radio, artwork, metadata, transcription model downloads, and license validation.

🧭 Three player modes

Choose the interface that fits your task:

Browser tab — the full interface with maximum space for the player and media library.

Standalone window — a focused player without unnecessary browser elements.

Firefox sidebar — keep music, video, or IPTV beside websites and other open pages.

The modes use the same queue and playback state, allowing you to switch without rebuilding your playlist.
