A little too bright, but suits the design language of Quantum well.

Beautiful! Love the rainbow shades. It makes the browser very modern and fun, and the fox at the end makes it Firefox-ish. I also love how you pick the darker hues for the left side, so that tabs can still be readable. Great job. Keep it up. :)

It has a very clean look to it, and the colors are nice.

Bright! Enthusiastic! Exciting!
Loved that turquoise tab highlight—a little detail goes a long way. :-)

I love the gradient and the powerful colors that bleed together. Plus I can still see my bookmarks and my buttons. So choice!
