Firefox email attachments - where are they?

Where/how does one find an attachment to an email when using Firefox? I don't use it myself, but a friend does and can't figure out where the attachments are found.

For example, in IE all I do is go down to the lower left-hand corner of the email and the attachment is shown there. I just click on it to bring it up. What's the process in Firefox?

Thank you in advance for any assistance.
