Reinstalled firefox has no norton add-ons

had malfunctioning vista.  clean installed win 7 pro 64, NIS 2010 and firefox 3.53.  after transferring some firefox profile data and upgrading to firefox 3.54, something was not right.  so cleaned out firefox and reinstalled 3.54.  after transferring limited profile data, i am left with a list of add-ons that does not include any of norton's.

 

is it alright not to have the norton's add-ons, in particular the IPS, since i usually enable that and disable the toolbar?

 

if not alright, how do i go about getting the norton add-ons back on the list for me to enable/disable.
