Make sure you go into your permissions for Fire Fox and enable the storage permission. This was the one trick I found in someone else's comments here. At first it didn't work. Once I gave fire fox permission to access storage it worked.
You can also do this on a mac, I did. Use Android File Transfer to plug your phone in and add files. Just look up how to make a .txt file using text editor.
