Hi, You can check if Norton has updated the toolbar by going to '''Tools''' ('''Alt''' + '''V''') > '''Add-ons''' click '''Extensions''' on the left and click '''More''' below the Norton entry and then the '''Homepage''' link. You can also try to install the [https://addons.mozilla.org/en-US/firefox/addon/add-on-compatibility-reporter/ Add-on Compatibility Reporter] that enables the disabled add-ons and see if the toolbar works properly as before. edit: Please also [https://support.mozilla.com/en-US/kb/Add-ons%20are%20disabled%20after%20updating%20Firefox see this.] ...............................................................................................................................
