NIS 2012 toolbar has disappeared from Firefox 15.0.1

Hi all,

 

this is a computer running Vista Home Premium Service Pack 2.

Norton Internet Security 2012 is the latest version (19.8.0.14). LiveUpdate has been run several times, no more updates are remaining.

Firefox is also the latest version (15.0.1).

Issue: the Norton Toolbar has disappeared, and in the Firefox add-on list of extensions, the OLD versions of the Norton Toolbar and Norton Vulnerability Protection extensions can be seen. The former is disabled and cannot be enabled, and the latter is still enabled.

Somehow, it would seem the the add-ons from the previous engine version of NIS 2012 are stuck in Firefox. Any ideas on how to correct the situation? :-) And before I forget: the Norton Toolbar shows up just fine in Internet Explorer 9.
