This usually happens if you use third-party font managers that store their fonts is a not standard location. Firefox on Mac uses a rather restricted sandbox and blocks access to most of the file system and thus blocks access to the font file if the font isn't in a standard system location. Firefox isn't able to access the requested font and falls back to a 'last resort' font that shows all glyphs as a '?' or an 'A'.
You can right-click and select "Inspect Element" to open the builtin Inspector with this element selected.
You can check in the Rules tab in the right panel in the Inspector what font-family is used for selected text. You can check in the Font tab in the right panel in the Inspector what font is actually used because Firefox might be using a different font than specified by the website.
You can check for sandbox security issues when Firefox has a problem to access fonts installed locally.
You can set this pref to 2 or 1 on the about:config page to reduce the sandbox security level.
- 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.
You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.
