Turn dark theme for YouTube on and off the easy way
Dark Theme for YouTube™ add-on converts YouTube theme to a highly customizable dark charcoal/blue theme.
note that as of version 0.2.0, the extension forces the built-in dark theme. This version does not allow customization. I have a plan to bring the customization back to the extension soon.
If you have ideas to improve this theme please open a bug report here:
Use the built-in dark theme (Material Design only)
