YT Speed od Arimtak

Lock your video playback speed with a single click.
Many video players require you to constantly hold down a key or the screen to watch videos at double speed (2x). This add-on eliminates that hassle by providing a simple lock function.
Features:
No more holding down keys: One click keeps the increased speed active. Pausing the video or clicking again automatically resets the boost.
Extended speed options: In addition to the standard 2x speed, this tool allows you to easily switch to 3x and 4x playback speeds.
Minimalist design: Extremely lightweight, straightforward, and clean—no unnecessary bloat.
