I've tried manually installing (Firefox says the addon is corrupt), I've removed gmp folders from profile, I've refreshed Firefox twice, play DRM content is enabled, it's not my antivirus (Comodo) and it's not my adblock (Adguard). I can't watch Netflix because of this. I don't know what to do more.

EDIT: Forgot to say this happened after today's update.

Try to toggle DRM off/on to see if that makes Firefox (re)load DRM components.

You can also use the Live Http Headers extension to check the server response when Firefox requests the file via the above mentioned DRM toggle.

It is possible that security software (anti-virus, firewall) is causing the problem. Try to disable security software temporarily to see whether that makes a difference.

I have tried to toggle DRM off/on multiple times, didn't work. Also I've turned off all my security software and it still didn't work.

I didn't understand how to use that HTTP addon though.
