I recall reading that the updates would start happening silently in the background. I still appreciate the announcement, but my guess is that next week I'll go to the About Firefox section and find that it waited until just then to download the update to version 18. I much prefer the way Chrome handles it where I go to check and find out it happened while I wasn't paying attention. Where's the hold up on making that happen? Did it happen and I just haven't flipped a setting?
