I have always come back to this theme on any computer I installed firefox on, I've been using it for about 10 years now (!), thank you very much to the author for creating it :)

大好きです。ずっと使いたい

Great artwork, tabs look amazing, and very good to use during night time where my screen isn't so bright when night mode is enabled.

Looks beautiful, the contrast between title text and theme is ok - text is visible. Worth recommending!
