User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:26.0) Gecko/20100101 Firefox/26.0 (Beta/Release)
Build ID: 20131215161728

Steps to reproduce:

The bug which was fixed a while ago describes this as best.

Steps to reproduce:

I am using an input of type file to upload pdf using ajax on Firefox 26.0

I'm using the following System and Browser:
Firefox (Package name): firefox-26.0-3.fc20.x86_64
Linux: 3.12.5-302.fc20.x86_64
Fedora: 20 (with all available updates, 27.12,2013)

Actual results:

I want to check the file mime type to be sure to get a pdf.
So I am using this javascript : 
var file = uploader.container.find('input[type="file"]')[0].files[0];

then I check the property  'type' of the file var. (file.type)

The value is 'application/octet-stream' instead of 'application/pdf' !

On a Windows System the Bug doesn't exist with Firefox 26.

Expected results:

The value of file.type should be  'application/pdf'.
Attach a testcase (HTML file), please.

I got the right type on Win 7, so Linux issue, probably.

On Ubuntu 13.10 with Firefox 26 installed, it works perfectly.
So is the issue only on Fedora?

Did you install Firefox from and not from the OS package?
This may be a duplicate of bug 373621. Take a look at the mimeTypes.rdf in your profile directory and look for entries referring to the pdf extension.
I installed the os package.

Sorry, this is not a Firefox bug. Something must went wrong during the upgrade process from Fedora 19 to 20.
I solved the problem by deleting the .mozilla folder in my home directory ("~/.mozilla").

Thank you for your efforts.

Yes my mimeTypes.rdf contains the wrong value for .pdf files.

<RDF:Description RDF:about="urn:mimetype:binary/octet-stream" NC:value="binary/octet-stream" NC:editable="true" NC:fileExtensions="pdf" NC:description="PDF-Dokument">
<NC:handlerProp RDF:resource="urn:mimetype:handler:binary/octet-stream"/>
