Update below...Paid for it at work. Have a license code. Can't find where to add it to Firefox at home. Very frustrating.... might have wasted $$$
OK.... when downloading a video... there is a place to update the license key.... there is a side bar slider to allow other options after clicking "more options" then Check or verify license key... THEN things seemed to update. NOT very intuitive or user friendly.... Take your blood pressure meds before attempting :)
