[RNSR] Geometric - Blue per Rina

◆ A "geometric" theme in blue tones, to be used on Firefox.
I made this (first) theme because I found this background picture on my computer, and I decided to design a theme.
This is my first shared creation, thank you for your understanding (please be lenient ! haha)
"[RNSR]" is my "watermark", which means "Rina Sero" in abbreviated form.
