If you open attachments with identical file names, there will only be one entry in the Download Manager, no matter how many times the attachment is opened. Multiple copies of the opened attachment, with slight changes in the file name,  are stored in the user's temp folder.

Reproducible: Always

Steps to Reproduce:
1.Create a file, let's say a MS Word named test.doc.
2.Send the file to yourself.
3.Edit the original .doc file to make any kind of change and save it.
4.Send the file to yourself again.
5.Open the attachment from the first e-mail you sent yourself, then close the document.
6.Open the attachment from the second e-mail you sent yourself, then close the document.
7.There will only be one occurrence of test.doc in the Download Manager. Open test.doc from the Download Manager.
Actual Results:  
When test.doc is opened from the Download Manager, the *first* downloaded instance of the file is opened.

Expected Results:  
It's unclear what should happened, since the whole process seems kind of not well thought out. At the very least, I'd expect the *last* occurrence of the downloaded file to open, not the first.

It seems to me that for any file that is downloaded or opened as a mail attachment, there should be a record for it in the Download Manager instead of ignoring subsequent downloads. The question would be, how to indicate identical file names in the DM. In Windows, SeaMonkey places the opened attachments in the user's temp folder, naming each additional instance of a file using -1, -2, etc. For example, the first opened attachment is saved as test.doc, then the next is test-1.doc, then test-2.doc, and so on. This is an important bug to fix for corporate users of SeaMonkey, since it's not uncommon for business users to circulate multiple versions of a file, using the same file name.
