I formatted my HDD and reinstalled windows 10 pro again on same HDD and system. After installing firefox and loggin into my account everything got synced except Bookmarks. For safety i had taken backup of my old firefox installation profile folders. However i tried to sync and also replace bookmarks file from old to new, but none of the things are working for me. In my last installation there is no file named places.sqlite but same is created in new which is causing my bookmarks not to load. Please note that usually all my bookmarks was automatically backed up to my account and it used to restore back again automatically without the need to take extra backup. But this time my sync was unable to restore my bookmarks. When i am trying to click options like import bookmark from HTML or Restore Bookmark from my backup file, sadly there is no action after clicking on relevant buttons. It is not just opening the dialog box for me to select file to restore the bookmark. I tried all options at my end but of no use. Please help as there is bug which doesnt open bookmark restore or import bookmark from other file
