Touch optimized browsers/making chrome/firefox better for touch.

I recently purchased a Thinkpad Yoga, I have been trying to find a better touch optimized browser. I know that IE has a version that is better for touch but I am not a fan of IE. I read about a chrome flag that enables touch optimizations but that flag is no longer present and firefox has stopped development of their touch browser. Does anyone know of any other browsers that are touch optimized or addons for chrome/firefox that somehow make the touch experience better?
