+ * See bug 480169.
+ *
+ * The purpose of this test is not to fully flex the sanitize timespan code;
+ * browser/base/content/test/general/browser_sanitize-timespans.js does that.  This
+ * test checks the UI of the dialog and makes sure it's correctly connected to
+ * the sanitize timespan code.
+ *
+ * Some of this code, especially the history creation parts, was taken from
+ * browser/base/content/test/general/browser_sanitize-timespans.js.
