You Tube videos won't play in my Firefox (but in Safari, for example, they do)
I cannot play practiacally any You Tube videos in Firefox, although they work fine in Safari. I just get this error message: "Video ei ole käytettävissä. Videon käyttöä on rajoitettu. Yritä kirjautua sisään G Suite ‑tilillä." Means roughly "the video is not available. Access to video has been restricted. Try to login using your G suite account".
I have tried clearing the cache, deleting cookies, disabling "use hardware acceleration", as adviced in some earlier comments I found regarding this problem. None of that seems to help.
