Got NAV 2013 installed, which also installs the stand-alone Norton Identity Safe. However, even though for 2+ days I have been running Live Update, identity safe extension is still disabled in firefox.
It is stuck at version 2013.2.4.2, even though version 2013.3.5.1 is available according to http://community.norton.com/t5/Norton-Toolbar-Norton-Identity/Firefox-20-amp-Google-Chrome-26-Support-for-Norton-Toolbar/td-p/937023
OS is Windows XP Greek 32-bit Professional, Service Pack 3, Greek.
