I tried to navigate away from the page in the middle of the song in Chrome and got a warning popup about leaving the page that was completely uncloseable by clicking on either option. I had to kill Chrome processes one by one until I randomly hit that tab :(

Shift+Escape in Chrome gives you the browser's task list. You can kill tabs without guessing there.

I could not get out of the pop up in any way, it locked my browser entirely.
