Auto-opens tabs in the background until I disable it. Totally useless in Firefox latest version

I have one machine when I attempt to merge with the online database it never finishes. It opens the this will take 10-40 seconds dialog, but then after 20-30 minutes I finally just kill the sync. I have no idea what I can do to get it working on this machine. Another one of my machines works fine and it is running firefox as well.

Сегодня исчезли все мои страницы с закладками, теперь только одна
страница с какими-то дилами по-умолчанию, а моих нет, их было сотня
минимум/ И внешний вид изменился

Show my bookmarks at the top! I don't want to ctrl+shift+b everytime!!!! its annoying!!!!

The computer gets super slow and then my bookmarks is duplicated.

Have to remove 20000 bookmarks, every week.

This started when I installed firefox...

Всё пропало.

Нет ни одной закладки.

Файлов *.sd нет. 

Список автосохранения пуст.

Что делать? Как вернуть мои  закладки?
