Yup, FF has just missed the mark on so many points that Chrome just blows past them. Any JS-heavy web applications (YouTube, HBO Go, Netflix) run like garbage in FF. Switch over to Chrome and they are buttery-smooth. Sucks to say this too as someone who's used FF since its beta.

For me Chrome and Firefox feel the same performance-wise. Are you sure you don't have some add-ons or other changes in your Firefox profile?
