I was able to do this with no issues a while ago, However, when recently attempting to do a backup, I have encountered an issue. Helium shows me this message: --- Backup Disallowed Firefox has disallowed backup of application data. Please leave a comment with the developer of Firefox and ask them to allow application data backup. --- Since this is disallowed, Is there perhaps a way to export all data within the app locally without going trough cloud sync?
