I have a problem with Firefox or another browser when playing a video. I have already tried the obi-codecs commands and installed the latest Nvidia drivers. It shows 3 frames for the first second and then hangs, so I don’t think it’s the codec or anything but the latest updates of OpenSUSE could be the problem. I installed OpenSuse two days ago and everything worked fine with Firefox to watch YouTube. OpenSuse Tumbleweed seems to be unstable.
