Unfortunately, Firefox's history saves the page address, but it wouldn't have the actual draft message from the page.

I don't know why a draft would disappear. It seems it should be saved until you either send or delete that message. Not sure we can help.

I'm crushed, I'd worked 3 days on a list. Thank you for trying. Appreciate it.

Wouldn't it appear in the sent or delete folder if I'd done either of those? It isn't there either, I've checked multiple times. Also in every folder I have set up. thank you again, Doatie

Don't know if this will be of any help, but here's what I just found :
