What about using ScopedTabbedBrowserDisplayer?

I don't think we want to create a browser if we can't find one.

Ah, true. 

What about FindTabbedBrowser then?

+Browser* FindBrowser();
+
+// Opens a new settings tab in |browser| with the given |disposition|.
+// If |skip_if_already_open| is true and settings is the currently displayed
+// tab, no new tab is opened.
+void OpenSettingsPage(Browser* browser,
+                      WindowOpenDisposition disposition,
+                      bool skip_if_already_open);
+
+}  // namespace chrome_cleaner_util
+
+#endif  // CHROME_BROWSER_SAFE_BROWSING_CHROME_CLEANER_CHROME_CLEANER_NAVIGATION_UTIL_H_
