Recently, I switched to Fedora 39. At first, Firefox was working fine, but after I logged into my Firefox account, the fonts of some languages stopped rendering, and this started happening with almost every site that was using system fonts.

That is about code points for Bengali.

In Firefox 119 Fingerprinting protection has been added to Enhanced Tracking Protection in Strict/Custom mode (Suspected fingerprinters) what affects accessing local fonts. To include user installed fonts, modify this pref on the about:config page:

  • about:config => privacy.fingerprintingProtection.overrides => -FontVisibilityBaseSystem,-FontVisibilityLangPack

You can open the about:config page via the location/address bar. On the warning page, you can click "Accept the Risk and Continue" to open about:config.

Hi, I am facing the same issue on firefox 126.0.1 on debian 12. I have followed the solution given by @cor-el but that doesn't seem to fix it. Please let me know if I am doing something wrong or if there is an alternate solution. Thanks.
