> We have plenty of challenges to overcome but it's nothing that can't be fixed. We're fully aware of some of the frame-rate issues on the really low-end devices (like in the video) and are actively working on improving that (it's a main priority to get 60FPS). This is the real boom to the web community. The fact that Mozilla has to make these things work. I get frustrated when I do a translate3d(-100%,0,0) on Chrome for Android and it's not buttery smooth. Or I use onscroll to achieve an infinite scroll list and it causes scrolling to be laggy. I'm sure the Chrome (and Safari) teams are aware of these issues and working on them, but to Mozilla they are absolutely essential. This will put pressure of Apple and Google to put a stronger emphasis on web app performance.
