I think it’s a bit naive to think that what Mozilla is lacking is a good CEO. A CEO cannot magically make Firefox the default on Android or have the most visited website in the world shove it down your throat. A CEO alone also cannot improve webgl or webrtc Performance without sacrificing development time on other things. I can’t think of any major problems Mozilla has that are caused by or could be solved by upper management, they simply don’t have the resources and outreach that google does.
