NIS 2012: Engine 19.9.1.14 installed, but Firefox toolbar 2012.5.15.2 isn't

WIN7 Pro SP1 32b; Firefox 22

 

I just upgraded to Firefox 22.  I know about the vulnerability protection incompatibility, but my toolbar is the older version 2012.5.14.2 instead of 2012.5.15.2.  How can I fix this?

 

BTW, NIS 2012 was just installed a few days ago after running NRT two times.

 

(1)  I don't want to go back to NIS 2013 as I was having problems with CCSVCHST.EXE.

 

(2)  I don't want to NRT/reinstall.  That will take 2-3 hours.

 

Of course, this will probably resolve the next time Symantec releases another NIS Firefox hotfix.

 

Thanks.
