Odd thing here, some (not all) videos on Twitter don't play. I get the first frame with the blue play button, but when I click it, it goes black with no sound. Some videos work, particularly the longer ones. Animated GIFS do not work.
I have tried nearly everything I found on the internet: new profile, clearing cookies/cache, changing about:config settings, using safe mode: nothing worked. Chrome does not play also, but it does not show a black screen, it freezes in the first frame (i.e, the blue play button simply vanishes).
I also have tried to access the video URL directly, it also does not play. But if I download the video and play it locally with VLC, it DOES play. Funny thing, this.

I am currently suspecting that it's a codec problem in the browsers. I went to html5test.com, it says that my Firefox does not support MPEG-4 ASP and H.265. But in the YouTube HTML5 page (https://www.youtube.com/html5) all checkboxes are marked.
So, I'm out of ideas. Please help.
