I'm not browsing benchmarks :-/
When I do then chrome will have an advantage.
Meanwhile, in the real world, a JS engine can be half the speed of the Chrome one and the browser can still be faster, because blocking ads is what gives you the biggest speed up.
All the performance advantages in the world fail to matter if you're still loading ads.
On my Android phone, Chrome opens web pages noticeably (and consistently) faster than Firefox. And I wasn't using a stopwatch. I am literally making a sacrifice to use Firefox.
