Search reports by browser:

font-weight: 600 and font-weight: bold are not equivalent. The browsers stretch up their fonts when you use 600. For a really correct bold font you must use bold or 700.

Mozilla exhibits a similar bug only on Mac: any text with font-weight: 600 appears as normal, non-bold text.

This is correct according to the CSS specs: "The keyword 'normal' is synonymous with '400', and 'bold' is synonymous with '700'."
