This is my go to extension for keeping my youtube videos at 2x speed. Though I have noticed with youtube's API changes that the extension doesn't always work. Either a new window or reload of my browser is needed to get it to work.

Edit 2024/7/14: The extension works really well still but doesn't always seem to run when loading up youtube. Sometimes I need to reload the browser to get the extension features to work

2024/9/26: The issues listed above have gotten worse where the extension doesn't appear to be active as I will have no preset settings working. Unable to narrow down the cause as some tabs it works others it doesn't. A new browser session doesn't seem to effect it

2024/11/16: I no longer get any features of this extension working.
