I'm getting missing fonts (Blackboxes) on MapboxGl on FireFox v64.0 using Mac only (PC works fine)
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. If you want to look at the working site click here: https://www.fox4news.com/traffic
If you need any more information please let me know.

I think that this page uses WebGL.
You can check the graphics section "Help -> Troubleshooting Information" (about:support) page for messages about WebGL.
You can also check the Web Console, but I do see a lot of warnings, so this might not easy.
- "3-bar" menu button or Tools -> Web Developer
