At first it was a bit of a strange to see yellow color, I wanted something darker, but now this theme has become my favorite :)

c'est beaux

I like the pastel colors and pretty birds. I also like that it doesn't mess with the viewing of my tabs. Thank you.

I've been using this theme for 2 years or more now and I love it.
However, there's a bug on 21/9 2K screen, there is a 60*85 pixels "black zone" on the top left of the screen (only for firefox, it's not my screen's fault :-) ). I continue to use the theme tho, my favourite :-D
