Video Speed Master

Video speed control + background playback, all in one extension.

Adjust the playback speed of any video or audio on any web page — from 0.07x for careful listening up to 16x for fast-forwarding through lectures. It can also keep media playing when you switch to another tab or window, so your videos never stop just because you looked away.

Key Features

- Variable speed: 0.07x – 16x, via slider, preset buttons, or keyboard shortcuts
- Force mode: keeps your chosen speed even on sites that try to reset it back to normal
- Background playback: video keeps playing in background tabs and windows — great for lectures and podcasts
- Global or per-tab: apply settings to all tabs at once, or tune each tab individually
- Per-site memory: each website remembers your preferred speed automatically
- Shortcuts: Shift + ] faster · Shift + [ slower · Shift + \ reset

How to Use

1. Install and open any page with a video or audio player
2. Click the toolbar icon and drag the slider or tap a preset
3. Turn on "Background playback" if you want media to keep playing when you switch tabs
