That's because of Firefox and Claws Mail using a different temporary
directory under certain circumstances.

For the full story, see http://bugzilla.redhat.com/956380
and the ticket linked there.

The Fedora packages of Claws Mail contains a README.Fedora, which 
points out that setting the TMPDIR environment variable for your user
account can fix it. Then both applications will use the same directory.
