Firefox does not close the file descriptor of local ogg files. Disk memory of deleted files which have a file descriptor open is not freed.

Reproducible: Always

Steps to Reproduce:
1. copy/download testcase to /tmp
2. open /tmp/vuvuzela.ogg
3. wait till finished/close tab
Actual Results:  
"lsof | grep ogg" reports open file descriptor

Expected Results:  
no open file descriptor after ogg file has finished/tab has been closed

The file will remain open until the garbage collector runs and cleans up the media element, and its nsMediaFileStream. If you wait around long enough after closing the tab, the GC will run, and release the file handle.

You can force the cleanup of resources by loading the file in a video element and setting its src attribute to "".

e.g.:

<video src="vuvuzela.ogg" autoplay controls onended="event.target.src='';"></video>
