Amazing. Reminds me of the old Netscape Modern theme a bit. Looks great.

Simple, solid non-distracting colour. I like it.

Es el tema mas sobrio y agradable de todos. Lo usaba antes con el viejo firefox pero lo habia perdido de vista. Es refrescante encontrarlo de nuevo en el Firefox 60+

My favorite theme!

Though I have the same issue as reported by the the user 14546869: with hi-res display (2560x1440) in full-screen the blue bar where the tabs are, cuts of at the left corner of the browser window. I do not observe this behavior on FHD or lover resolution displays. As 14546869 user noted, "the graphic you used seems to be not width enough". I have the same issue also with your other theme "Gloss. Black".

Could you please adjust that?

Because it is not too black, it is easy to see. Just good.

easy on the eyes and still can read everything!

My favorite theme!
Just one thing that bothers me.
I have large widescreen monitor and the blue bar where the tabs are cuts of at the left if my browser window is in fullscreen size. The graphic you used seems to be not width enough :( Maybe you can adjust that!
