Firefox 82 has fuzzy fonts

As soon as the Firefox got updated to 82, all fonts on all websites look fuzzy.

Not on mine - Using with Plasma 5.20. You might need to give some more details about your system if you want further help.

Hi, it’s probably related to fontconfig package update. Please check if this config file helps:

I am not sure what info to give, besides those on my profile:
Branch: Stable
Desktop Environment: KDE
CPU: AMD Ryzen 9 3900X
GPU: Radeon RX 580 Saphire
GPU Driver: amdgpu
Kernel: 5.9

@Kukaraja thanks, but I am not sure where to place that config file.

Into folder ~/.config/fontconfig/

Thanks. lcdlight improves it a bit, but it’s still noticeable fuzziness. Chrome/ium renders it just fine.
