Hello wdsautter,

In addition to the above posted replies   (and I will be nice) :

Your system details show one dodgy extension :   "Safer Search 1.0.1 ";   would you please remove it ?

To do so, you'll need to go to the Firefox menu (≡) <big>→</big> Preferences <big>→</big> Add-ons <big>→</big> Extensions.

Then   (just to be on the safe side),   would you please run the malware scans that are listed in this article :
