My Firefox chrome never looked much like any of those. I remember when the "classic" theme came along in 2011 and everyone praised it for being more compact and efficient, I was already long-accustomed to an even more compact layout that takes up very little vertical space and is still very similar to how I have it set up today.

From a user's point of view customisation of the UI has gotten slightly more difficult over the years, but it's still not that much trouble and so far it's always been worth the effort.
