No fonts in firefox/thunderbird after update

Help

Hey there!

I just did a routine update of my system and the fonts in firefox and thunderbird broke after updating :confused: From what I can see, there is no other problem in the system.

When debugging I indentified that the problem doesn’t happen if I launch firefox using X11 (but well I’d like to have the fractionnal scaling).

Does anyone have any idea of what could cause the issue? I tried resetting font cache, restarting the computer, starting firefox in safe mode, etc. to no avail.

For reference, here is my configuration: GitHub - TheEaterr/nixos-config · GitHub
