PiP is one of those things that never seemed particularly useful to me until I started using it, and now it’s one of my favourite features

For some odd reason I don't get the PiP icon on the firefox demo video. It works well on different youtube videos though :)

By default the button only shows on videos over 45 secs long

You can change the default in about:config media.videocontrols.picture-in-picture.video-toggle.min-video-secs

Many thanks :)

No problem

I feel like it used to be 30 seconds, although I may be incorrect
