I did not put it on my FireFox but I do see a comment that Centerpoint is the creator of this extension. Centerpoint is the creator of my virus protection that I just updated. I'm trying to get a hold of them to ask about it.

The Harmony Web Protection extension is either installed by the "Endpoint Security Client" or ZoneAlarm Security Suite ?

Could be installed via a policy: policiesStatus: 1
