Firefox won't start playing webm videos until the complete video is in downloaded/cached.

http://lac.linuxaudio.org/2013/video.php?id=78 <-- example video or http://lac.linuxaudio.org/2013/recordings/09-02-baalman-480p.webm

Server side seems fine: Content-Type is OK (video/webm), apache2.2.22 (returns 206 for Range:0- requests),..

Problem exists with

* Nighly 24.0a1 (2013-05-17) Linux 32bit
* Firefox 21.0
* Iceweasel (10.0.12 from debian)

Works fine with other browsers (e.g. chromium, epiphany,...) Might be similar to https://bugzilla.mozilla.org/show_bug.cgi?id=502894#c1

Is this a bug? An issue with HTML5

Thanks in advance

Recent crashes of certain multimedia contents (this includes Youtube videos, certain flash games and other applications) in conjunction with Firefox are most probably caused by a recent Flash 11.3 update and/or a malfunctioning Real Player browser plugin.

In order to remedy the problem, please perform the steps mentioned in these Knowledge Base articles:

Flash Plugin - Keep it up to date and troubleshoot problems

There is no flash involved.

I see the same happening and the full video (?) gets loaded.
If I disable WebM (media.webm.enabled -> false) then I get the Gecko media player plugin that displays the video after a short buffering.
