Firefox 14 won't pick up norton toolbar

I have followed Tony Wiess' note on this with no luck. I have run live update and have got 2012 19.7.1.5 of NIS installed. Firefox has Norton Toolbar 2012.7.3.1 disabled with no option to remove it. Tried a number of reboots, but no change. I have uninstalled and reinstalled Firefox 14 and it still has 2012.7.3.1 and says it is incompatible with firefox. Last thing I tried was a reset of firefox to try and lose all add ons, but when it came back it picked up Norton Protection, but still had Norton Toolbas 2012.7.3.1.

Any ideas as to how I can get my toolbar back please?
