I upgraded to v. Firefox v. 17.0 this evening after running a manual LiveUpdate and received an error message that the Norton Toolbar v. 2011.7.13.2 is not compatible with FF17. The latest update for the Symantec Intrusion Prevention v. 11.1.1.5-3 extension seems to be working fine.
Has Symantec stopped supporting NIS 2011 for Firefox users, or is an update for the Norton Toolbar still pending?
