Moreover I've = noticed that when I edit the default value of=20 "security.sandbox.content.level" from 4 to 2 in "about:config" then the=20 problem disappear and the fonts are properly displayed in --pure and=20 --container env. I was trying to install all possible fonts, running=20 'fc-cache -rfv' and analyze the icecat logs with "MOZ_SANDBOX_LOGGING=3D1= "=20 to include blocking paths into the=20 "security.sandbox.content.read_path_whitelist" but still I couldn't fix=20 this issue with the icecat default sandbox level. Any ideas how to solve = it in Guix System and what are the side effects of using=20 "security.sandbox.content.level=3D2" in --pure env? Kind regards!
