Identity safe on Firefox (windows 10)

Confused on directions to install Identity safe in updated Firefox for windows 10. Directions say to look under view toolbars and to insure the add on is active. Firefox no longer shows the Norton identity safe add on, and cannot locate it in the search option. I cannot make any sense of the visual directions shown in the Norton protection directions in the identity safe tab configure for firefox steps. Display shows a web brower page with a Firefox tab in the Symantec corp web site. Cannot find any such window.
