With new Firefox add-on, is it possible to download a file with login info as a backup?

I have been using the Toolbar and ID Safe with Chrome [which I switched to when it stopped functioning with Firefox].  I keep an update file with all my logins - which is easy to do with the ID Safe component of Norton Security [which I use].  I prefer to use Firefox, and I like the new Firefox add-on, and use it.  But what is not clear to me is if it is possible, while logged on with Firefox, to directly download a copy of my login info to my machine.  Right now, what I do is to open ID Safe using NIS, and then create my backup.  Is it possible to do this within Firefox, so I would not have to login to ID Vault through Firefox, and then do it again within Norton Internet Security.  [With Chrome, once I have opened my ID Vault with NIS, I don't have to login again to use it in Chrome.]
