Latest Firefox update has caused a conflict with Norton 360 "Web Safe" feature when using Yahoo search - no icons visible, i.e., green check mark for OK, gray for not enough info in Norton user data base, RED for unsafe "Web Safe" feature functions in Firefox if Norton tool bar search is used (powered by ASK) - functions in IE8 when Yahoo search is used. Problem is isolated to Firefox / Yahoo search. No prior history of similar problem. == Operating system == Windows 7
