before it was ok (green, yellow, red signs)
now thses sgins do not show,
I checked tools->addons/plugins, it is enabled.
I send to email to mcafee, they send me a auto-reply:
"visit us at http://service.mcafee.com for all of your McAfee related support needs."
but in fact I submitted the email at http://service.mcafee.com, contact page.
so their reply is not helpful.
