简介
Adjust playback speed and volume
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 square bracket keys [ and ] to adjust playback speed. Backspace and \ resets to 1x.
You can also speed through un-skippable advertisements at 16x speed, handy for news websites.
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 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.
Coming soon: Auto-"skip" un-skippable ads

Added bug fix for slider value not updating after restarting the extension on Youtube Shorts.

Update August 2023 - Version 2.0.3
Now works with most websites that have video, including iframe videos. Please report any sites that do not work and I will look into why.
Added alternative keyboard keys for changing speed, the two square bracket keys and the backslash key [ ] . Some websites like YouTube change the caption size with the + and - key, so the [ and ] key can be used instead.
Added finer speed increments of 0.05 for speeds under 1.5x.
