YouTube Speed Controller

Use your Mouse 🖱️ or Keyboard ⌨️ to slow and accelerate the YouTube playback speed of the video you are watching.

Click the '+' button to increase and '-' to decrease the playback speed. Controls appear on the top-left corner of the video player and can be dragged where you prefer.

This extension makes you save clicks. No more clicking through YouTube sub-menus while you try to find the interesting parts of a video, just adjust as you go. Settings page let you customize your experience even more.

⭐Features:

- Adjust video speed with a single click/keyboard stroke.
- Works instantly after installation (refresh the page if it does not).
- Change default speed steps (e.g., from 0.25 to any value) in the settings.
- Change minimum and maximum speed (e.g., from 0 to 16) in the settings.
