[arch-general] Problems with movie playback (HTML5)

Hi, After recent update I have problems in HTML5 movie playback. In Chromium, films on YouTube are buffered but don't want to start at all. Pressing play/pause has no effect. I can manually move playback to different time but this only causes new frame to show without playback. In firefox I can play video, switch on another one but I cannot reload page - firefox freezes completely. System updated with pacman 16.11.2015. Anyone seeing similar things? Regards, Łukasz
