+/**
+ * nsISessionStore keeps track of the current browsing state - i.e.
+ * tab history, cookies, scroll state, form data, and window features
+ * - and allows to restore everything into one browser window.
+ *
+ * The nsISessionStore API operates mostly on browser windows and the tabbrowser
+ * tabs contained in them:
+ *
+ * * "Browser windows" are those DOM windows having loaded
+ * chrome://browser/content/browser.xul . From overlays you can just pass the
+ * global |window| object to the API, though (or |top| from a sidebar).
+ * From elsewhere you can get browser windows through the nsIWindowMediator
+ * by looking for "navigator:browser" windows.
+ *
+ * * "Tabbrowser tabs" are all the child nodes of a browser window's
+ * |gBrowser.tabContainer| such as e.g. |gBrowser.selectedTab|.
