1057509 - input type=file does not properly handle accept with specific MIME types

Status: RESOLVED DUPLICATE of bug 826185

(Firefox :: Untriaged, defect)

Description

[C Farrell]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:31.0) Gecko/20100101 Firefox/31.0 (Beta/Release)
Build ID: 20140715214327

Steps to reproduce:

Create a file upload element on an XHTML5 page:
<input type="file" accept="audio/x-wav,audio/mpeg"/>

Load the page, click the file input to show the File Upload dialog.  I tested with 31.0+build1-0ubuntu0.14.04.1.


Actual results:

The File Upload dialog showed all file types.  In the dialog a select was present with options:
* All Files (selected initial when the dialog shows)
* All Supported Types
* WAV Audio
* MP3 Audio


Expected results:

All Files should not be an option when specific MIME types are listed in accept.  All Supported Types should be selected when the dialog shows.
