After updating to NIS 2010 addons in FF stopped working.

I have just updated from NIS 2009 to NIS 2010 through norton update center.

 

Several addons in FF 3.0.18 stopped working immediately following that.

 

The following addons are still present in the list of addons and do not appear to be disabled. They no longer work.

 

Norton toolbar 3.7.2

Goole toolbar

Google notebooks

Addblock plus

 

Norton IPS is no longer in the list of add-ons.

 

Norton toolbar, norton IPS and google toolbars seem to be working fine though in IE8 after the update.

 

What should I do in this situation?

 

I also have Norton Systemworks BE installed and if at all possible would like to avoid using NRT.

 

Thank you, Alex.
