Love it. I was cautious whether the animation would be distracting, but it is subtle enough that it is not distracting. Several colleagues have asked "what browser is that?". Good work.

My only request is to improve compatibility with Tree Style Tab (TST) add-on, as the animated image gets stretched and becomes blurry in the TST side bar.

I'll be keeping this theme.

LM22.2 great animation to see if my system hung or not; also a dark theme variant that has a great highlight color that's visible and non-intrusive.

I love the smooth animation and the dark colors!
