From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I had a similar thing happen recently following a NixOS upgrade. I wonder if it's something that changed in Firefox.
In my case, the solution was to set
useEmbeddedBitmaps = true
in fontconfig. Which is unlikely to be directly helpful to you on Fedora, but maybe there's an equivalent option somewhere?
