Downloaded attachments now come in as genericlly named ashx files instead of their native format and names. How do I get this to go back to normal?

I am running Firefox on a MAC with OS X 10.6.8 and when downloading a file the files are now coming in as generic "attachment.ashx" files instead of coming in with their original name and extension. I can change the extension to the original and the file will open but it is a pain to have to rename and change the extension for every download. This just started and I want to know how to get it back to the previous way of downloading. Thanks!

Outlook Web Access sends an illegal Content-Dispositon header to Firefox. This is no longer allowed in Firefox 8. Firefox 9 will have a workaround for this so that Microsoft has time to fix their software.
