I have Firefox 27.0.1 and Norton Antivirus 21.1.1.7. Norton Toolbar will not work. Suggestions???

I have Firefox 27.0.1 and Norton Antivirus 21.1.1.7.  Norton Toolbar will not work.  I had Norton 360 prior today.  Subscription was expiring, my office computer was transferred onto the license for the Norton Antivirus.  I have uninstalled and reinstalled Firefox.  I have run Live Update multiple times.  Norton toolbar is still disabled in Firefox.
