Poor frame rate, not smooth at all

A calming animation and a beautiful blend of colors unifying the address bar with other elements. I've hidden tabs with user css so this single bar looks amazing to me. Sadly, Firefox 66's animated backgrounds take a non green amount of energy to work: about extra 15 watts in my rig.

excellent

Merveilleux! J'aime beaucoup la délicate animation, les couleurs!

Really pretty, but any deselected tabs to the right are unreadable.
