This can happen when Firefox has a problem to access locally installed fonts because of sandbox security issues. https://wiki.mozilla.org/Security/Sandbox
You can set this pref to 2 or 1 on the about:config page to lower the sandbox security setting.
security.sandbox.content.level = 1
close and restart Firefox to make the change effective.
If '1' still doesn't have effect then try '0' to disable the sandbox.
If this didn't work then undo/reverse the change and reset the pref via the right-click context menu to the default value.
Type about:config<enter> in the address bar. If a warning screen comes up, press the I Accept the Risk button. At the top of the screen is a search bar.

Thank you so very much! Problem solved when I changed the level to 1 (the "I Accept the Risk" button was pretty intimidating, but thanks to your guidance I persevered, and it seems fine now.)
Glad to help. Safe Surfing.
