I am trying to find the mbox files in .thunderbird which is where the 
Thunderbird help documentation says they should be.

With the Evolution MUA, also using IMAP on gmail.com the mbox files are 
easily seen. in .evolution

I suspect that I should post on a Thunderbird mailing list and ask where 
the mbox files are located on my Desktop, or, if using IMAP, as I am, 
there are no mbox files on my Desktop. Probably it's one or the other.
