What happened to the little house icon that took you directly to your home page on a MacBook?
I think you mean the browser, but as I'm not entirely sure...:
Browser: Right-click Safari's toolbar/address bar, select Customize Toolbar, and drag the Home item to the toolbar.
Finder: Open a new Finder window, and, if necessary, navigate to your home folder. Drag the icon in the window title bar (it's called a proxy icon) to the Finder's sidebar.
