YouTube Music Videos - Blank - Loading - Errors out until you refresh

Question

I've been having issues with music videos on YouTube with the latest version of Firefox. I would go to YouTube then browse the music and then select a video and it would play through the advertisement then video would be blank while trying to load then error. However if I refresh the page it works. This is quite annoying. Any other video plays without receiving this issue/error. It only seems to be Music Videos from what I have seen so far.
If I switch to any other browser this issue doesn't occur.
I have also asked my friend if his does the same thing and he also Firefox and what do you know same thing, different ISP, also only has this issue with the browser Firefox.
I hope the Firefox team could find the issue and release a fix with their next update.
Thanks.
