http://firewallerror.com popup ad locks Safari
T 5 May 2015: I received an email, that had been sent to one of our "Educational Institution's" "System email addresses", which had been delivered to one of our "Public Folders"
It said it had a VoiceMail embedded & when I {Stupidly} selected the Green "Play" button,
a new Tab opened in Safari entitled "Home" with the URL Address:
firewallerror.com/?traffic_source=1693
which had "Action Required" & "Help" in a Black Header Bar & a Popup was in front of that, which could NOT be "OK"d out of to get to Safari System Preferences
and all COULD BE DONE was to Exit Safari, & COULD NOT go to any other Tab or New Window
The PERSISTENT Popup had the following text:
[{Safari} logo in Upper Left Corner]
