This is a seven-star theme. A loving sunset. A good contrast and easy to the eye!

Норм из многих просмотренных, если бы еще вкладки страниц в открытом состоянии заставить играть переливами +5 было бы вообще

Very Soothing

Looks beautiful when I install, but as soon as I switched tabs it disappeared and FF goes back to normal. Any idea why this might happen?

edit: I figured it out earlier, it was because I also had ColorfulTabs extension also installed - took it off so no conflict and voila, it worked! Rating revised :}
