Tempo - Media Hub by GenPepe

Tempo turns every tab that plays audio or video into one card in a single panel. Instead of hunting for the tab that suddenly started playing, you open Tempo and control everything from one place.

WHAT IT DOES

• See every playing tab at a glance: artwork, title, artist, progress
• Play or pause any tab — or pause everything at once
• Seek, skip ±10 seconds, adjust volume, mute
• Previous and next track, wherever the site supports it
• Repeat the current track
• Jump to the tab that's playing — and jump straight back to where you were

YOUTUBE CHAPTERS

When a video has chapters, Tempo reads them and shows a table of contents. Jump to any chapter, step to the next or previous one, or loop a single chapter on repeat — handy for lectures, tutorials and language practice.

LIVE STREAMS

Twitch, Kick and YouTube Live are recognised as live rather than as ordinary videos. Where the player keeps a DVR window, Tempo shows how far behind the live edge you are and lets you seek inside that window.

ON THE DESKTOP

Drag a card up or down to reorder your list — the order is remembered. Drag a card sideways to pull that tab out into a window of its own.

ON ANDROID

Tempo opens as a full page instead of a small popup, so you can bookmark it and keep a permanent remote control for everything Firefox is playing.

ALSO

• Light and dark themes
• Interface in English, Russian, Spanish, French, Polish and Indonesian
• Keyboard shortcuts: Ctrl+Alt+Space to play/pause, Ctrl+Alt+Period to pause every tab (both can be reassigned in Firefox)
• No accounts and no analytics. The only network request Tempo makes is to YouTube, to read the chapter list of the video you are already watching.

Works with any site that plays audio or video through standard HTML media elements.
