I have used Firefox and syncronization earlier. I have syncronized my bookmarks from my computer 1 to another computer. Today I had to re-install Windows 10 because of an error in my computer 1. I checked before re-installation, that I can login to Firefox account. I trusted, I can get my syncronized bookmarks back to Firefox after re-installation. When installing Firefox after Windows installation, it only asked if I want to take my bookmarks from Microsoft IE or not at all. I used "not at all" and trusted to Sync service. When I went to Sync service, I got a notice "Syncronization will start soon". But nothing happened. I was afraid that it saves my none bookmarks to Sync and empties the real ones. My bookmarks are still in another computer. But how to get them vice versa back to the computer 1. Firefox User guide have pictures and advice which are different from how the newest Firefox is working. I have the newest Firefox version in both computers. Please help, how to get the bookmarks back?
