A thread about Firefox descended into a conversation about the free market. But is that really warranted? What I mean is, Firefox is an open source product, right? So isn't it just a matter of a feature to hijack the "the video turns into a little box" javascript function so it doesn't do that, or blocking it and detecting in some other way? I'm no web developer, but it seems like a feature or add-on should conquer it.
