@Flemnipod snowrider said in Youtube showing "Video Not Available":

Youtube has been working fine up until today when it has started showing the message "This Content isn't available. Try again later." on every single video. If I refresh the page it works normally.
This is only happening in this browser and all others work perfectly.
I've tried disabling everything that I can think of that may cause an issue but it's still the same.

I'm seeing something very similar on my setup. Videos initially show the "Content isn't available" message, but a refresh loads them normally.
