Question marks when viewing web pages

Posted

Hi,

I've been getting question marks instead of words (typefaces) when I load some websites. This isn't consistent. When I use Safari, everything is just fine. Even Chrome.

I've tried everything I could find worth trying in other peoples' queries with no luck.

This is super frustrating.

This likely means that Firefox isn't able to access the requested font locally and falls back to a 'last resort' font that shows all glyphs as a '?' or an 'A'.

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.
