Steps to reproduce:

When testing canPlayType('video/mp4) with javascript, branch 25.00 returns empty sring. Should return 'probably'.

var video = document.createElement('video');
var canPlay = canPlayType('video');

Actual results:

Returns emty string instead of 'probably'


Expected results:

Return 'probably'

with media.gstreamer.enabled = true

[13:08:19.717] var video = document.createElement('video');
[13:08:19.723] undefined
[13:08:26.661] video.canPlayType('video/mp4')
[13:08:26.666] "maybe"


with media.gstreamer.enabled = false

[13:09:27.141] var video = document.createElement('video');
[13:09:27.145] undefined
[13:09:28.293] video.canPlayType('video/mp4')
[13:09:28.298] ""

tested in Mozilla/5.0 (X11; Linux x86_64; rv:25.0) Gecko/20100101 Firefox/25.0

So, WFM.
