Video Speed Master автор BruttoBernd

Video Speed Master is a clean and minimalist Firefox extension that lets you control the playback speed of any HTML5 video on the web.

The popup interface is intentionally simple and distraction-free. It automatically detects videos on the current page and allows you to adjust playback speed in several ways:

Features

Slider for smooth speed adjustment

Preset buttons for common speeds

Direct numeric input for precise control

Works on all websites using HTML5 video

Dark and light popup themes with manual toggle

No data collection, no tracking, no ads

If no video is detected on the current page, the controls are disabled and the interface clearly indicates that no video is available.

How to use

Open a webpage containing a video

Click the Video Speed Master icon

Adjust the playback speed using the slider, presets, or by entering a value manually

The extension is designed to stay out of your way while giving you full control when you need it.
