I don't think Mozilla is lost - although they lost a battle. The war continues, and now it's all about Servo and Rust. Don't be too shocked if a new browser-based-OS comes out in time, too; with the new tech. The timing for such a thing is better every day as HTML5 adoption increases, etc. And remember how far Mozilla fell once upon a time before an independent effort called Firefox revived them and then some. Rust has massive advantages. I do wish they'd look over at Chromium's license and change their license terms so that they could be almost assured that they were building the future because they were building for everybody, though.
