I applied a browser CSS change to fix it, and now I think it's great.

:root { --tab-min-height: 30px !important; }
:root #tabbrowser-tabs { --tab-min-height: 30px !important; }about:config
I have the new tab theme, and the compact UI once again.
And if anyone is also trying this route - change `browser.uidensity` to 1 will restore the compact theme.
Anyway looked a lot worse in screenshots, with my system theme and tweaks I am actually liking how it looks. What I don't like very much is the new shield icon inside the address bar, looks more like a weird hexagon than a shield, but that's rather minor.
After using it, I simply don't care. It's fine either way to me.
So I switched to Firefox a few months back... It's disappointing that they've now made exactly the same mistake, but at least there's Firefox Color [1] that allows me to easily restore some contrast without spending time writing my own CSS.
But I don't know why I hardly noticed a difference. I mean sure it does look like a button, and I don't really get the point of it, but the thing I was worried about was the increased screen estate. Maybe it's because of my gtk theme, maybe it's related to fixes in hidpi UI scaling, but it actually seems to use less screen estate to me.
Am I crazy? Or are there other people that feel like its using less screen estate?
Personally it's unusable on my Windows 7 computer. I know it's a dead OS but still.
