I'm using Firefox v12 to open a hyperlink from a website that points to a filename.doc MS Word Document for download.

We are then asked to open the file with MS Word (Default), which our installed version is MS Word 2010.

Firefox then renames the file appending a .docx to the filename e.g filename.doc.docx. MS Word 2010 opens with error 'incorrect file format', which is correct as Firefox has renamed it.

Is there a fix or workaround for this?

Could you provide a link to a site that has this problem?

Do you save the file first so you can control the name, or do you open it directly?

You can try to delete the mimeTypes.rdf file in the Firefox Profile Folder to reset all file actions.

Hello Jscher2000,

I can save the file and it opens fine. It's when I open it directly, Firefox appends the 'docx' extenstion to the filename. If I continue to reopen from the web link, Firefox renames the file as so mydoc.doc-1.docx mydoc.doc-2.docx mydoc.doc-3.docx

I can open a .doc from a Microsoft site ok. I have the feeling it's the way the web server is reporting the mime type to Firefox. The link in question works fine in Internet Explorer.

best regards, Youngielinux.
