When Firefox is maximized, it puts the Firefox button, the tabs and the minimize/maximize/close button all at the same level along the X axis (so they all appear in a line).
But it does not do that when it's not maximized. When not-maximised, the tabs appear underneath the Firefox logo and min/max/closed buttons (as pictured below).
How do I make it do that always, even when it's not maximized?
Maximized:
Not maximized
