StreamSpeed

About

Fine tune the playback speed of popular streaming services, including Netflix, HBO Max, Amazon Prime Video, DisneyPlus, and YouTube, from 0.1x to 16x speed. Use the slider bar, the + and - keys, or the [ and ] keys to adjust playback speed. Backspace and \ resets to 1x. 

Slow playback to 0.1x so you can see sleight of hand in magic tricks, or watch an action scene unfold in slow motion. Speed up an audiobook 3x or DIY video 10x so you can get through them more quickly. Binge watch an entire 10 hour season on 3.3x speed in 3 (I suggest turning captions on at higher speeds)

You can also scroll to change the volume up and down - handy for watching movies from the couch if you don't have a remote for your speakers. Click the 'Scroll Volume' button on the left side of the slider bar to enable, and click again turn off scrolling volume and regain normal scrolling functionality.

Update January 2026 - Version 4.1.1
Small fix for Amazon Prime video, and added a final container check as a failsafe in case a valid element to target wasn't found to make the extension more resilient to site changes.

Update April 2025 - Version 4.1.0
Added fix for Disney Plus. They had made a DOM change with multiple videos being added, so the speed changing function was targeting the wrong video. The fix has been tested and is working.
