In both Chrome and Firefox On Windows 10 at 100% zoom in the browser and 100% screen scaling this looks blurry; the pixels in the font don't line up with the pixels of my monitor unfortunately.
Quite likely this is because Firefox 68 didn't support subpixel positioning so it aligned all glyphs to full pixels. Chrome 80 (and Firefox 76 in some configurations, or if gfx.text.subpixel-position.force-enabled is enabled) uses subpixel positioning if possible, which improves kerning of normal fonts, but in the case of these "retro" fonts, it's harmful. Maybe it's possible to adjust the glyph metrics so they're aligned to full pixels even if subpixel positioning is used, but I'm not sure if this can be really be done so it works everywhere.
Firefox 68esr (left) is crisp but has too tall characters(?) resulting in a gap in lowercase 'o'.
Chrome 80 (right) has this problem and is blurry in addition.
