Is Youtube Custom Speed safe?

Clean risk

This extension lets you set custom YouTube playback speeds from 0.0125x to 16x.

You can choose preferred playback rate values in the options menu, then change a video's speed using buttons at the bottom of the YouTube player. It also works with YouTube's default Shift + , and Shift + . keyboard shortcuts. The extension can run on www.youtube.com and stores its settings locally through the browser's storage permission.
