My problem is that emojis look bad on Firefox compared to Edge_128.0.2739.79. Two examples are attached (left half of both pictures is Edge, other half Firefox).

I've tried (to no avail): A] Disable hardware acceleration in settings (w/ firefox restart). B] Setting "gfx.font_rendering.cleartype_params.rendering_mode" from -5 to 5 (w/ 10+ firefox restarts). C] Setting "gfx.webrender.quality.force-subpixel-aa-where-possible" to true (w/ firefox restart). D] Disabling all addons. E] Setting new firefox saparate clean install.
