Firefox has been painfully slower than Chrome by great magnitudes for me on a cheap Dell Windows laptop. I have almost identical extensions except for NoScript which might be the culprit, although it is also the main reason why I use FF over Chrome (and for enabled extensions on private mode, which defeats the purpose of private mode but it has been used more as a "don't save history" mode than private mode if you know what I mean).
