There's a difference between "broken" and "not the way I use it / am used to". Mozilla released a video explaining the transition of tabs [1]. Still don't like it? Right click somewhere on the title bar and deselect "Tabs on Top"

As for the status bar, just hit "ctrl+/".

The best thing about Firefox is that if there's something you don't like, there's probably an add-on for it. Try searching for add-ons that do what you need. [2]
