If you're using Zone Alarm, see https://support.mozilla.org/bm/questions/1450820.

If you're using ZoneAlarm, see this.

The answer is untrue.  This extension is installed by ZoneAlarm without the users (or the Admin's) consent.  There is no "Deny" button;  the "Confirm" appears to be automatic.  Working with Support now to try to remove it; the standard instructions didn't work.

[Ronegade]

This extension is apparently removed if one turns off Web Protect in ZoneAlarm (I find all that a huge nuisance anyway).  BUT, what isn't clear is, after making changes in ZA, one has to reboot for them to fully take effect.  Nice little gotcha . . .
