I installed Sync on my computer (Windows Vista) and my laptop (Windows 7 Starter) this last week. I first noticed sync working on my laptop as the theme and bookmarks from my computer had imported to the laptop. Now a few days later I've to my computer and the changes I made to the laptop Firefox have not been applied. I tried Syncing but I get an error message. I made sure the laptop was active and not in sleep mode. Also, does Syncing not affect extensions/addons? == This happened == Not sure how often == I've used it less than a week and wasn't paying close attention until today.
