[Mozilla FIREFOX] What's html5 player.js?

[Ignoranta]

Dear Helpers,

Believe me, this is not-explainable, but I'll do my best.

All I can say is, whenever using Firefox, out of the blue, I'm getting a page full of codelines at the end of my FF which is a tab that's impossible to close (I end up closing others, whereas it remains there), and I have to restart my FF for it to go away, which is the only way to get rid of it.

Its link: http/s.ytimg.com/yts/jsbin/html5player-en_GB-vflphciOs/html5player.js

I just chose to take a snapshot of that page and post it.

If you DO know what to do about this burden, please, explain.

Thanks in advance to all in our great community!

Cheers!

Ignoranta

Reinstall Firefox, report back if the issue is still there.
