User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 GTB7.0 ( .NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 GTB7.0 ( .NET CLR 3.5.30729)


I have some wvx files on my server that point to media using relative links e.g., media.wvx contains the following lines

<ASX VERSION="3.0">
   <ENTRY>
    <REF HREF="media.wmv" />
   </ENTRY>
</ASX>

The problem occurs when clicking on a link to the .wvx file e.g., http://www.myserver.com/media.wvx. If I click on the link in IE, WMP plays it perfectly, however, in Firefox, clicking on the link opens up WMP which then gives an error "Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to compress the file."

Reproducible: Always

Steps to Reproduce:

1. Create a sample media.wmv file & a sample media.wvx file in the same folder.
media.wvx should contain the following lines

<ASX VERSION="3.0">
   <ENTRY>
    <REF HREF="media.wmv" />
   </ENTRY>
</ASX>

2. Ensure they are playable locally
2. Place both files on your web server in the same folder and ensure the server is sending the correct mime-type
3. Visit http://www.example.com/media/media.wvx
4. Select "Open With" - Windows Media Player and click OK

Actual Results:  
WMP gives an error message -
"Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to compress the file."

Expected Results:  
WMP should play the media without problems.


a) I believe the issue is that IE resolves the relative path to the desired location while Firefox does not. I don't know which browser's behavior is technically correct.

b) Saving the .wvx file to the desktop and opening it from the file gives the above-mentioned error - as expected.

c) The server returns the correct mime-type.
Please report this to the MS Plugin developers.
You can not compare IE with all other browsers because IE is using an ActiveX Plugin and all other browsers are using NPAPI Plugins.

The "media.wvx" file isn't touched by Firefox at all and Firefox doesn't resolve links in it. The file is given to the Plugin and it's the plugins fault if it can't handle it.

Closing old bugs in the Plugins component. We aren't going to track issues in 3rd-party plugins in the Mozilla bug tracker. In addition, support for NPAPI plugins will be removed at the end of this year; for more details see the post at https://blog.mozilla.org/futurereleases/2015/10/08/npapi-plugins-in-firefox/

If there is a serious bug in Firefox, it needs to be filed in the "Core" product, "Plug-Ins" component.
