So I loaded up a clients web page on a mac using the most current release of Firefox v64 and the mapbox that is being used on that page does not display any fonts correctly. Everything looks fine if you access the website using a PC and using Firefox v64 and if you go to a previous version of Firefox v63.3 on a Mac the map also displays completely fine. I don't know if anyone has experience this or has any insight on what might be the issue.
