Fonts displaying as question marks on certain sites (such as the autofill on Google).

Veröffentlicht

HI- Recently lots of my fonts have started displaying as question marks on certain sites (such as the autofill on Google). If I uncheck the box in prefs that allows websites to use their own fonts, it's fine. But then the sites look nasty. I've reinstalled Firefox 69.0.2 but its no better. It's a work Apple mac so I can't access all the settings but the issue is only on Firefox. Please don't make me use Chrome! Thanks

This likely means that 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 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.

The same thing happened to me when I upgraded my MacOS to Catalina.

I tried disabling all fonts to try to isolate a conflict and was not able to figure it out. Any help here would be appreciated as it is very annoying.

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.

When I hover over ".LastResort" it highlights the question mark boxes. It says what is used is Helvetica, which I have loaded on my computer, but it is not loading for some reason. Any thoughts?

This probably means that either the Helvetica font is corrupted or is installed in a location that isn't allowed (whitelisted) in Firefox.

Try to uninstall this Helvetica font via Font Book.

Did you make sure that only this one system Helvetica font is installed and not other fonts that report as Helvetica ?
