Since I ran the last update my fonts don't show properly. ...they show as "A" in a box. I'm on a mac, running 10.10.5. I've changed all the fonts in preferences too. Any ideas?

This can happen when Firefox has a problem to access locally installed fonts because of sandbox security issues.

You can set this pref to 2 or 1 on the about:config page to lower the sandbox security setting.

  • 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.

I don't understand what that is... what am I supposed to do with that?

more options

Type about:config<enter> in the address bar. If a warning screen comes up, press the I Accept the Risk button. At the top of the screen is a search bar.

Search for security.sandbox.content.level and set its value to 1. Restart Firefox.

If the problem is still there, repeat the above but set the value to 0.
