I found the visibility terrible and I could not see which tab was active. I open the extension settings and the settings are simple, complete, pretty and exactly what I was looking for. 0% BS. 100% Came to rate 10/10 but in stars so that is 10 half-stars summing up to... 5 stars! I talk too much.

Looking good.

Adds one of the more subtle features I was missing when switching from Safari. Works great!

Actually it's very slow...

so good! Wish you could change the speed of the colour transition since its quite fast and would be so much better for people sensitive to light/people with epilepsy! :))
