I noticed this this AM and assumed it was something around Firefox or otherwise specific to me. The situation for me was not being able to create a new playlist when saving a video because it would trigger all of the keyboard shortcuts while typing. It would mostly work...until you get to a letter like "f" and fullscreen blows away the modal. This is a bit of a cautionary tale around the dangers of hijacking "normal" behavior: when a bug happens, you break really, really basic things.
