Firefox extension Integrated Gmail lets you add other Google services such as Google Reader, Google Calendar into Gmail box. You don’t have to open another tab or window to read news or check your next appointment, they are right inside Gmail now. You can even add custom web pages or gadgets into the collapsible list. With this magic add-on, we are no longer need to put calendar in the sidebar.
