YouTube Speed Controller 作成者: router1941

Adjust Speed: Hover your mouse cursor over the speed text (e.g., 1.00x) to the left of the autoplay button and scroll up (speed up) or down (slow down).

Reset Speed: Click the speed text once with your left mouse button to return to normal speed.

Change Sensitivity: Click the Youtube Speed Controller icon in your Firefox toolbar. Drag the slider or modify the number box to change how fast the speed accelerates per scroll notch.

Zero Tracking: This extension runs entirely locally on your machine. It does not communicate with external servers, harvest browsing habits, or collect analytics data.

Minimal Permissions: It only requests access to the local storage API to save your layout preferences and isolates its runtime logic exclusively to youtube.com.
