My understanding is that a recent version of FF set up an auto update daemon that today downloaded and installed the above software to enable viewing protected content in FF. The only way I found out was a Norton message that it is safe. it does not appear in the update log (via advanced options). I have auto update turned off, and I expect this setting to be honored or at least to be clearly notified before accepting the FF version that contains this "feature." My concern is not limited to this adobe software, which may very well be beneficial. Rather, I wish to control the software contents of my PC. That's one reason why I use FF to begin with. It seems obvious that such a lapse works against mozilla's best interest, since people depend on mozilla to protect their security and privacy, and this lapse has reduced my level of trust. In additions, computers under change control requirements could wind up with an un-approved and untimely change, which can be a serious issue in some environments.
