I feel the same way. This is just a new way of windowing the content, not displaying 2 different sources in one screen.
I've seen a couple of this breaking the video out of the main layout, but not sure if it was this Firefox feature or not. I was pretty sure that once the video broke out of the normal layout, the original location of the video was replaced with ads playing without audio. I was immediately turned of by it.
