How?!
This is how example.com renders: https://i.imgur.com/MFo7ACg.png
Pay attention to how the word "illustrative" renders: https://i.imgur.com/lFJIEZG.png
See e.g. the boldness on e.g. the first "l"? Firefox's clearly has two very dark vertical strokes in adjacent pixels -- one black, one dark blue right next to it. Its rendering is substantially bolder than Windows's. I can understand if you personally prefer that, but how can you claim they look the same?!
