When Vimeo is loaded in an iframe that doesn't have fullscreen permissions then it doesn't show the fullscreen button (on Mozilla Firefox).

Couldn't lity just add the mozallowfullscreen webkitallowfullscreen allowfullscreen props to the iframe it creates? Is that an option somewhere?

Nevermind, lity already adds allowfullscreen and it was a problem with some custom code that was adding allow="autoplay; fullscreen" but not allowfullscreen and it seems that the other versions haven't been needed in a long while. My bad! :)
