Youtube doesn't work in Firefox

Hi everyone I've got a very (VERY) **** annoying problem. It's starting to freak me out.

Firefox doesn't play any youtube videos. From youtube itself or from other site with embedded player. I just see spinning dots forever.

What I've done to fix problem: 1. Restarted browser many times - no effect at all 2. Refreshed browser - sometimes I see effect, sometimes no. Anyway videos stop playing after first restart of the FF or even before it. 3. I deleted and re-installed FF - no effect 4. I deleted all of my profiles and FF itself and then reinstalled it - everything was fine, but only for a half of a day. 5. I also disabled synchronization - no effect. 6. I disabled all addons - no effect.

Any other browsers (chrome, edge, others) play youtube as cool as always. I'm 99% sure I've got no malware or viruses on my PC.

Windows 10, Firefox 53 (64 bit)

What should I do now?

Youtube currently uses the HTML5 player. https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues

Of course I know that youtube uses html5, how is it supposed to help me?
