I agree on this old UI failure...I thought for a moment it had been reverted, but then realized I had installed the Custom Tab Width add-on. The realization brought me back to my own extreme frustration with coming back to Firefox and finding this behavior being the default and not easily changed. I'm generally OK with a lot of stuff being in add-ons. But, this one is not one of those things. I really don't think I should have to install a plugin to decide not to have a scrolling tab bar (I hate the scrolling tab bar).
