Firefox is also faster at DOM navigation: https://jsbench.github.io/#b39045cacae8d8c4a3ec044e538533dc https://jsbench.github.io/#b39045cacae8d8c4a3ec044e538533dc You can see from that set of benchmarks (once you run them) that Chrome will top out at around 45 million ops/s in the fastest cases. In Firefox the top cases are a stress test of memory access speed. My old desktop with DDR3 reports numbers like 850 million ops/s while my newer laptop (4 years old) with DDR4 memory, both otherwise slower, reports something around 1.2 billion ops/s. Years ago when I discovered those benchmarks I remembered other users reporting as high as 5 billion ops/s. I would be curious what somebody reports now with fast DDR5 memory.
