    Default FF 3.0.3 and 2.0.0.17 associating DOC files with application/applefile on WinXP Pro

    There seems to be a file association problem with Firefox on at least Windows XP Pro in my environment. Firefox seems to associate DOC files with application/applefile (which makes no sense), which makes it impossible for some emails to make it through certain scans (Content-Type to extension comparisons). I've been able to replicate the issue on FF 3.0.3 and 2.0.0.17 on Windows XP Pro in multiple environments with MS Office 2007 installed.

    Emails with DOC files attached in these environments receive the following:

    Content-Type: application/applefile; name="Test Doc.doc"
    Content-Transfer-Encoding: base64
    Content-Disposition: attachment; filename="Test Doc.doc"

    I can't seem to get Firefox to switch from application/applefile to application/msword. If the same attachments are attached via IE 7 environments, they are attached with the correct content types of application/msword. I've posted on Mozilla's forums for ideas.

    When MS Word 2007 or any other MS Office product isn't installed, DOC files are attached at an octet-stream:

    Content-Type: application/octet-stream; name="Test Doc.doc"

    Any ideas?

    NOTE: Could not replicate on a Vista x64 Ultimate machine running FF 3.0.3 with MS Office 2007.

    I see this a lot. For uploaded files, Zimbra blindly trusts the MIME type sent by the client, but about 1% of my users have a bad MIME type for at least one common file type.

    MimeTypes.rdf - MozillaZine Knowledge Base

    You can probably change the app type in Preferences. Else, remove the mimeTypes.rdf file (in a randomly named subdirectory of Documents and Settings\user\Application Data\Mozilla\Firefox) and restart Firefox.

    I've entered an RFE for the general issue. Might be closed as WONTFIX, but at least it's on the record. Bug 32536 - Zimbra too trusting of MIME-type sent by client
