> I'm sorry, but I'm unable to access this YouTube content. This is possible for a number of reasons, but the most common are: the content isn't a valid YouTube link, potentially unsafe content, or the content does not have a captions file that I can read.
Not all video elements are for stand-alone consumption. For example, there are "hero" videos in landing pages, enterprise solutions requiring smart overlays, or imagine a component in an online video editor.
Firefox also have no plans to support the Picutre-in-picture web API: https://www.w3.org/TR/picture-in-picture/.
See, for example, this bugzilla issue: https://bugzilla.mozilla.org/show_bug.cgi?id=1611831
One needs to consider three approaches of forming an interest circle: shared (an explicit list of members), individual (each user maintains several lists of his friends) and automatic (extracting subgraphs of user relation according to attendance).
What we are currently willing to provide is the combination of them all. Automatic extraction is fun to play with, but you always want more control over it. We are also preparing to launch something similar to the shared model, where you could subscribe to an organizer which is basically a group of related events.
