Hello. 2 month ago I use FireFox with this account (***@yandex.ru), and i update my Windows from 7 to 10. Now, i install Firefox (my favourite browser:) ), and I use my account, but I don't see bookmarks, password and etc. Yes, I select all data to sync. What could be the problem? I do something wrong, or my account is clear? _{edit: removed personal information for your protection. (philipp)}
