Hello, Can you explain in more detail by what you mean when you note "unable to get the confirmation signal from mozilla" Does this mean the app is stalling out when you try to log in? Or spinning wheel of death, or something totally different? While I am not quite sure what you are seeing, logging out, uninstalling, and reinstalling, then logging back in may help. It sounds like it could be an authentication issues as the update went through. Installing fresh should clear all the app folders and refresh your authentication abilities.
