My Firefox ToolBar is different?

I bought a new computer (finally) with the Windows 7 home edition. I downloaded Firefox 5. My toolbar use to say things like "tools," etc. Now I have got 'Most Visited, Getting Started, Latest Headlines." I tried to find a download for the Firefox tool bar. But all I can find is add-on's for the tool bar, not the bar. Even when I re-downloaded the Firefox page.
