@Drizzle, I actually had an error in the post I made, it was in ABOUT and it checked for and automatically d/l'ed and installed via a re-start FF 16.0.1. Had to do this on two computers. This never happened before, I'm pretty sure I'd be told there was an update available via a popup before? Either my memory has failed or a setting had changed, but if it was set to AUTOMATIC (TOOLS -> OPTIONS -> ADVANCED -> UPDATE) before and the first time I used FF after a version release it would usually tell me one was available and d/l it? Did NOT happen this time, I assumed as they knew there was a serious problem with 16.0 and stopped the auto feed? Maybe the problem is on their end?
