Does this require some special test environment (special OS, special builds of firefox/chrome)?

Because for me chrome vs firefox (both 115)

  - ubuntu desktop: 148(+-2.2) vs 126(+-6.5)
  - android phone: 95.8(+-2.0) vs 78.5(+-4.3)

So it looks like chrome is faster and delivers a more stable performance while firefox is slower and more inconsistent on performance

Extensions can have a measurable effect on the benchmark, be sure both browsers have no extension, or the same extensions with the same configuration.

Chrome has ublock and very few others, Firefox only ublock

I suppose it is about nightly 117

Adding my anecdotes: on an M2 mac mini

  - chrome 114: 472 ± 30
  - firefox 115: 390 ± 22
  - firefox 117: 420 ± 12

Small update: Firefox 117 on Android phone 75.4(+-6.4) so still there

The linked graph is for Firefox Nightly (currently 117) running on Windows.

I get 260 for chrome & 160 for firefox on win 10.
