STABLE version -- 4.3.9.248

[CodeMonkey]

Are these browsers based on the same Chromium version?

That's correct. I tried to keep testing consistent. Each browser tested was on base build number 86.0.4240.198. Now I'm not sure what is being measured by the "store" metric, but Cent scores about two thirds of the score I get from other Chromium-based browsers. The calculate and render score was largely the same between each browser tested.
