Its almost perfect, I really like that the timer keeps going if you have youtube open regardless of if a video is playing or not.
It could do with more settings and the timer shouldnt pause if the video you are watching is not the current open tab.

Sometimes it continues counting wasted time even though you are not on yt anymore, but its good nonetheless

Straightforward and useful, as of 4/20/2026 works perfectly.

10/10 extension with great customizability and abundant number of features. very much love that youtube music can now be excluded!
