Good morning, I have two Firefox accounts: embecobat@gmail.com famillebuy@free.fr While I was connected with famillebuy, I changed my account to go to embecobat. A synchronization was done with the data still displayed from family buy. I took everything from my embecobat account. Can you cancel this synchronization? Embecobat is a professional account... Thanks for your help. Sincerely. Mallaury Buy
