The animation is beautiful but the color scheme needs to be changed a bit. I don't know which element it is, but sideberry's highlights are nearly invisible with this theme since they are grey on black....

Somehow it's the only theme that's *actually* black and has a themed sidebar. I don't even mind the animation

My absolute favourite of all time, with Dark Magic, also by Nicothin, being a close second! My only issue is that the visual difference between the selected tab and the rest is so minimal, I often close the wrong tab on accident. I understand most people probably find that subtle difference part of the appeal, but it drives me up the wall. Still, I love this theme so much, I keep coming back to it. I uninstall it or select another one (Dark Magic, usually), thinking, "It's close enough, it'll do the trick, and then I won't keep messing up with the tabs." But no. I love me some lazy stars swirling in the vastness of space as I browse. Thank you for sharing this with us. <3

the best theme

Muito bom o tema. Não polui os olhos, o que é bastante difícil com os temas do firefox.
