password sync data
I recently had to reinstall windows, and then reinstalled firefox. When I synced firefox settings, and transferred all of my passwords. On the computer I transferred the passwords to (new firefox download on new installation), it states (in firefox security section) that all of my passwords were used on the date I did the sync. I am wondering if the sync made it look like I used the passwords on that date, or if the party that did the reinstall (a local computer store) tried to hack my accounts and passwords. I am changing the most sensitive account passwords, but there are so many passwords it would take me many hours to do so. If someone can confirm that the sync made it look like the passwords were used to access the accounts, but the accounts were not actually accessed, I do not have to worry. However, if the sync process does not make it look like all of my passwords were used, then I need to be concerned about my accounts being hacked. If someone can help me with this I would appreciate it.
