I like the new Opera Browser on my Ubuntu 14.04 very much und would like to keep. However Opera cannot handle the Video Offers of Spiegel online and other Online Newspapers such as www.faz.de.So I am forced to switch back to Mozilla again which is a lot slower but it can handle everything so far.
Since I am not a Computer expert, I need a solid information how to handle the problem on a simple way.. Thank you
