Unsubscribe is the way to go, thank you son :)
This tip came just in time for me to save me as a Firefox user. I disabled the skype click-to-call and now Youtube works again as before.
I had already started using Chrome for Youtube and was slowly moving more and more activities to that browser.
Thanks!

If you’ve lot of subscriptions, signed out of YouTube account and see if the issue persists.
