Max resolution in firefox is 1080p even for 4k videos (html5 enabled)

Hello guys,

I'm using Firefox 43, and I noticed that I can't see videos in higher resolution than 1080p, it seems to be a firefox issue. I tried to play the video in chromium and the resolution was good (meaning 2160p).
I do some research in the forum and also in search engine and nothing about this. it seems that this occurs with firefox for a lot of users, you can try with this video : https://www.youtube.com/watch?v=SXZ3qWAvbVs
If you don't use Chromium you can confirm that this video is available in 4k using youtube-dl
I also checked for those function in about:config
media.mediasource.enabled
media.mediasource.mp4.enabled
media.mediasource.webm.enabled
media.fragmented-mp4.ffmpeg.enabled

And all of them are enable.

If somebody could help, it would be great.

Thanks
