As for "all new WebAPI's" you'd be surprised how many of them were first implemented in WebKit. Enlighten us: https://wiki.mozilla.org/WebAPI https://wiki.mozilla.org/WebAPI WebRTC? Chrome—fall 2012. Firefox—summer 2013 I don't think so: https://hacks.mozilla.org/2012/11/progress-update-on-webrtc-for-firefox-on-desktop/ https://hacks.mozilla.org/2012/11/progress-update-on-webrtc-... Note that at this point Firefox had DataChannel, and it would take Chrome months to catch up there. Firefox also introduced the used audio codec. That said it's a bad example, because WebRTC standardization is currently a strong effort between both companies and it'd be great for the web if more standards went this way rather than ending up with having to try to standardize half-assed implementations from one rendering engine. (cough WebSQL cough)
