Youtube video speed controls on the extension icon. Enables you to fast forward beyond 2x on youtube. Very lightweight!
I made this extension for myself because the other similar extensions annoyed me by modifying the Youtube page (the body) or injected annoying speed controls which obscured the video player. This extension doesn't use content scripts meaning that it doesn't run idle in the background. This makes the extension very lightweight and only runs when you want it to run.
This extension will always be free. Please contact me if you have any questions or ideas for improving this extension.
