Chapter 7), the menu contains only those Web sites you visited in the current tab. In other words, short-term history is tied to individual tabs if you're using them; otherwise, it is tied to individual windows. 2. Choose the Web site you want to revisit from the history menu. Navigating history more quickly with the Go menu The second method of navigating short-term history is to use the Go menu at the top of every Firefox window. Like the Back and Forward menus, the Go menu offers quick access to the last ten Web sites you visited. But unlike the Back and Forward menus, the Go menu isn't tied to any particular tab or window, and it remembers your recently visited sites even if you restart Firefox. In that sense, it's more like "medium-term" history. An example should illustrate that this is less confusing than it sounds. Open a new Firefox window and navigate to CNN.com, then to ESPN.com, and then to Google.com. Right-clicking the Back button offers quick access back to ESPN.com. Now open a new Firefox window. You can see that the Back button is no longer lit up; that's because you haven't visited any Web sites in this particular window yet, so you have no Web sites to go back to. Even so, when you open the Go menu in this new window, you see CNN, ESPN, and Google near the top of the Go menu. REMEMBER Unlike the Back and Forward menus, the Go menu abides by the history setting with respect to how many days' worth of history to remember. (I discuss this setting at length in "Extending, shortening, or disabling long-term history," later in this chapter.)   In other words, the Go menu is a great tool when you know you visited a Web site recently but you aren't sure if it was in this window or that window, this tab or that one, or even today or yesterday.           Delving into Long-Term History Many browser designers seem to think that because short-term history is the one you'll be accessing most frequently, it's okay to turn long-term history into the abandoned, dusty wing in the library basement - you can trek down there every so often and get what you need, but it won't be easy. The problem with this approach is that it's ridiculously simple to access the last 10 pages you visited but nigh impossible to get to that 11th. Firefox puts your long-term history at your fingertips so you can quickly return to that elusive page you found last week. By default, every Web site you visited in the past nine days is stored; to change this setting, see the later section "Extending, shortening, or disabling long-term history." You access long-term history from the History Sidebar (shown in Figure 6-3), which you can open by choosing Go History or by pressing Ctrl+H (Windows) or +Shift+H (Mac). The History Sidebar offers two means of finding the page you're looking for: browsing through a list or, if you remember part of the page title, searching for it. Figure 6-3: The History Sidebar allows you to search and access all of the Web sites you have visited in the past nine days. Browsing long-term history The History Sidebar uses the familiar concept of folders to organize your history and allows you to switch among five views via the View button next to the Search text box:
