I have tested your issue on latest Firefox release v52.0.2 (32 and 64-bit) and latest Nightly (Build ID: 20170405030213) and could not reproduce it. I have opened the link from comment 0 in an old profile and the video was clearly visible. This is also happening with a new profile.

Just an observation. The video has a HD button. The resolutions of the video is influenced by the internet connection speed, this is automatically set if the user hasn't changed this setting. At the lowest resolution 144p the video is unclear and the text is blurry. The clumsy movement of the objects is caused by the low internet connection and the loading state for the video. At 1080p the video is clearly visible.
