Hello, I have been using xmarks with firefox 55 to sync my bookmarks. Today, I decided to switch to Firefox Sync. I have de-installed that plugin and joined firefox sync. I have logged in to firefox sync on another computer with firefox 55 latest update. The existing bookmarks are not being synced. Accessing tabs from the other computer works fine. However, when I add a new bookmark to one of the computers it is getting synced to the other. Also, when I move a pre-existing boomark into a pre-existing bookmark folder, even that folder is created on the second computer just with that one moved bookmark. The other bookmarks from that folder are not synced. Somehow Firefox does not seem to recognize the pre-existing bookmarks for syncing. May that have to do with xmarks handling them before? I uninstalled the plugin completedly. No change. Thanks for any help.
