Everything is well, except that, unfortunately, it conflicts with YouTube's built-in "Playback speed" function, as well as with other add-ons, e.g., https:// addons.mozilla. org/en-US/firefox/addon/youtube中文配音/, which causes freezes and makes rewinding impossible.

Keeps disappearing (I'm on latest version 1.10). It's good when it works. Could do with being able to scroll mouse wheel to change speed.

I appreciate this extension, but please add the ability to create keyboard shortcuts for adjusting speed! I would really like the ability to use "+" and "-" to adjust instead of being stuck using the default controls.

EDIT 8/11/2025: Speed control on the video player is no longer aligned with the new YouTube player design.
