I like the new tab center, but not the position/shape.
As is, the top area of the browser always seemed like a wasted space to me. It just has the MF logo on the left and the seize\close buttons on the righ; in between is just empty space. I would like for the tab center to be ‘hidden’ there so that if the pointer\arrow hovers over it a pop-up window (of reasonable size) appears with a (scrollable) list of tabs. Is that an option? Seems much cleaner to me.
