content-type for MS Office XML

[jscher2000]

The relevant bug report seems to be Bug 381936 - Content-Disposition filename not obeyed when choosing to "Open" a file whose extension doesn't match Content-Type.

Excellent sleuthing.

(I suspected it was related to the way files are handed off to the Windows shell: if you don't change the extension to one associated with the user's selected application, then you will not get the application you requested -- you will get the default application for that file extension.)

Unless you can save your files with an application-specific extension like .docx, I have no other suggestions. XML is a common file extension that is not unique to Microsoft Excel or even Microsoft Office, and there don't seem to be any MIME types for Microsoft Office files with an XML extension.

Thank you, this lead me to another blog post which describes my problem exactly.

I see there's nothing I can do about it in firefox without breaking it in IE at the same time.

Thank you guys for your help.
