On certain sites, the font is replaced with a "?" in a box. How do I fix this?
I have tried turning the "let site use it's own font" on and off in preferences and have downloaded a new version of Firefox to try to fix it if it was a corruption issue. Nothing has worked. The same problem is affecting my home computer and my work computer so the problem seems to be a Firefox issue. Help.

We have seen cases where a box with all '?' or all 'A' is displayed that might be related to using a Last Resort font that displays all the glyphs with one same character.
You can try to set this pref to 1 on the about:config page.
- security.sandbox.content.level = 1
You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
