The difference in the screenshot seem pretty subtle to me; I think the main difference is that in the drop-down menu, Chrome is using subpixel antialiasing, whereas in Firefox it's grayscale-only. Not sure whether that's really a bug, or just a difference in how the rendering pipelines end up handling things. Interestingly, in the page behind the drop-down, the situation is the opposite: Firefox has subpixel AA, while Chrome has grayscale!

Verified this issue and it's still reproducible on Firefox versions 122 and 124.
