All excel attachment files in Outlook web app (email) are renamed "attachment.ashx", losing their original file names. Why? And how do I fix this?

While the email displays the attachment with the "original file name.xls", when I click and download, it is called "attachment.ashx", and I lose all the original downloaded file names. This started happening about 3 weeks ago after a Firefox update. Suggestions for a fix?

Outlook Web Access sends illegal Content-Disposition headers and this is no longer allowed in Firefox 8. The server needs to be fixed. See:
