That's simply not true. I regularly find Firefox to be faster than Chromium. And the opposite is also true, but the difference isn't big. None of the two browsers has a clear advantage, and neither gets in the way of normal usage, nor in the way of heavier usage (I do some light data crunching and 2D convolution in the browser).

that may be great for stand up comedy, but on HN we tend to expect slightly more substantiated discussions.
