How Firefox implements synthetic-bold varies across different platforms, actually, depending on the features of the (platform-specific) font rendering backend it's using. It uses the paint-multiple-times-with-a-small-offset approach when the font backend doesn't seem to offer a "better" synthetic-bold option.
