I can't believe I didn't notice this feature sooner, but I only just discovered it during the weekend and thought it was a new youtube feature till I saw Linus's gaming browser video.
This is super convenient especially if you use a single big monitor like me and want to watch (stream) a video while multitasking or even gaming!
You can even resize it, though it seems diagonal only but still you can make it really tiny and still have lots of screen real estate and it's always on top of your applications too.
What do you firefox users think about it so far?
