After installation of Firefox 5.0.1 I have lost options "Pictures", "Maps", "Blog" etc. How I can put them back?

Firefox 4 and later versions use a new build-in home page named <b>about:home</b> with a Google search bar on it. That about:home page only shows some snippets and has a button to restore the previous session if applicable. * If you want a home page with extras then set another page as the home page like www.google.com or www.google.com/firefox as used in Firefox 3 versions.
