I'm using latest Opera on Kubuntu 16.10. For some time all chromium based browser abandoned support for flash player (including pepperflashplayer). As HTML5 players are more and more used that shouldn't be an issue. But, for some reason, when I try to play a video on Facebook it reports an error that Flash is unavailable even though Facebook claims to use HTML5 player.
I'm able to play videos e. g. on YouTube. I'm also able to play Facebook videos in Chromium.
Anyone had a similar problem and found a solution?
