I've been using this add-on for a while and it's great.
However today I noticed that the layout of youtube had changed and it was no longer in dark mode, and the option to enable dark mode was also missing.
It seems that this add-on has caused this because as soon as I diabled it I got the new layout with dark mode again.

Well build add-on.

Life has become flawless after installing this extension......Great job mate!!!!

It's totally working. Awesome experience :)

A great app with many features and works flawlessly, and bugs are patched very quickly.
