YT Custom Speed Button от Samrat Barai

This is an extension that bypasses youtube's 2X speed limit and adds an extra button on the youtube bottom bar, the Speed Control Button. It contains a list of pre defined speed that can go far beyond just 2X. The list can be customized by clicking on the extension icon. The buttons are designed with youtube's native element styles, so it blends seamlessly with the other buttons and also has an text indicator for currently set speed.

This Add-On was created to help me fast forward through videos without being restricted by YouTube's limit. Hope this can be helpful to someone else.
Thank you.
