After Installing new system on my laptop and singing in to my Mozilla account nothing was restored from it. Everything is empty as it is completely new account but I created this one few years back and never had a problem with a sync. Hopefully it will be restored since I had large amount of important bookmarks. If you can check and resolve it please. Thank you.
