My mom just reset her windows 10 laptop because it crashed. When she reinstalled and synced her firefox account, her bookmarks were crazy. There are out of order and there are both current and old bookmarks from my account, her account, AND my dad's account. The weird thing is that none of the accounts are connected in any way, except that the computers are in the same house, which shouldn't affect anything. Why is this happening and how do we fix it?
