No, I'm not actually assuming that, because I realize there is only negligible difference between major browsers today in terms of rendering performance, and none can approach the rendering performance of native UI frameworks on mobile.
But I am assuming that a browser offering a gigantic leap in UX through native-like rendering performance will entice web app developers to recommend that browser over others, because it's nigh impossible to build a consistently 60fps non trivial app with native-like interactions and transitions on the web today, while Servo and Webrender aim to make 60fps on the web the norm rather than the exception.
I occasionally run Firefox (out of nostalgia, idealism, or the need to test a site), and the fact that it is so slow is absolutely what stops me from switching back to it.
Nah. One piece of rendering I particularly care about is interactive SVG performance, and -- while, as another thread says, we can't expect smooth 60 FPS experiences from current desktop browsers -- the difference between Chrome and Firefox is the difference between 15 FPS and 1 FPS.
Recently all toolbar icons in Firefox have been converted to SVGs [1] and in the process several performance problems were found and fixed or are in the process of being fixed [2]. You may want to try out a recent Nightly build.
I adopted chrome because of the speed, but I keep using it because I'm used to it and it works fine. I know my way in and out of chrome's dev tools. On firefox it would be a struggle to figure out a web development routine.
