I have been using both the Documents module and the File Manager to upload files to my DNN intranet portal using both IE and Firefox.  For some reason, when I attempt to download files from the site using Firefox, all file types (pdf,exe,zip) come up as application/octet-stream.  I understand this is a standard MIME type for exe files, however all files are comming up as this type when downloading in firefox.  Also, even if I continue to download using Firefox, the files download without an extension and are thus unrecognized by windows (I also noticed that the files names are changed/cut-short).  If I add the file type extension after the d/l completes, then the file will work just fine but users of the site will be lost and have no idea what the extensions should be.  When using IE, all files download fine, with the correct extensions and names.  Please Help!!  I at first thought it was a module issue, however I removed and added the modules again and no luck.  I am also experiencing this problem when downloading directly from the file manager.  Any ideas or help would be greatly appreciated, I am somewhat new to DNN so please be aware.  IS there something I need to edit in web.config or another DNN file?  Is something wrong with IIS? Or is this something with Firefox?  Either way, HOW DO I FIX IT!! Thank you very much for any help.

I am having the same problem. I am using Firefox 1.5.07 (requiring folks to upgrade to version 2 dos not seem to be a reasonable option if that would fix the problem). This was not a problem with the previous 3.x version. I wonder if it has something to do with the new public/private file directory capabilities. Have you had any success tracking down a solution.

Thank you, Thank You!  That worked like a charm, I have been trying to figure this out for more than a week!  I cannot believe it was something so simple.  Seems like this is a big flaw in the way DNN/Firefox handles these types of files (not sure which is causing the problem).  Is this something that should be reported as a DNN bug? Where are such issues reported?  Either way, thanks again for your help I tried everything I could think of and was almost ready to reinstall DNN.
