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?

I am in the process of switching from Chrome to FF. I have a new install of FF 55 and the first extension I installed was FVD Speed Dial. For some strange reason when I open a NEW tab the focus is in the address bar but the cursor is at the end of the actual address (moz-extension://09670e0f-5e6d-4ce0-9993-651eaf4f1c0f/newtab.html) in the bar so if I type something I am just typing at the end of the current address. It should select the address in the address bar upon open so I can type right away. The way it is now is a pain because I have to click off the address bar and then click the address bar again to start typing. It works correctly in Chrome. I am not sure why it does not work in FF.

I have tested this to make sure that it is FVD Speed Dial that is causing this. If I disable all extensions then everything works as it should. If I activate FVD only then this issue starts. Is there a setting somewhere that I am missing?

when starting speeddial, it opens noumerous windows/tabs in background and slows down until nightly is no more working.

Every time I quit Firefox and then launch speed dial is empty again. Backups - nothing. Every single time!

Sync of Speed dials taking forever, still not been successful has been stuck on dials for last couple of hours.

I only use google search as previous people also said.. please Google or a search provider option thanks
