Thank you for the additional information, I found a Firefox support thread talking about a similar issue: https://support.mozilla.org/en-US/questions/1269532
Maybe you can try to reboot first (the font issue might be caused by a macOS update), and if the '9's are still displayed as dashes after that you can try the procedure described in the support thread.
