Features & Capabilities

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.

Is Video Speed Master Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Video Speed Master requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Video Speed Master may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
