Firefox 60.0.1 does not display some text correctly

Firefox 60.0.1 seems unable to display some fonts. Most of my e-mails and numerous websites exhibit this problem. I've attached an image of what Firefox displays. I've attempted to change the default font in preferences, but the problem persists. Have others experienced this problem. Have any solutions been discovered?

BTW, if I paste this giberish into a text editor, it displays the text correctly.

Thanks for your consideration.

You can check for sandbox security related 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 noticed this advice in a previous post when I was looking for solutions; tried it, but it did not solve the problem.

Have ou tried this yet? Type about:preferences#content<enter> in the address bar. Across from fonts and colors, press the Advanced button. On the bottom, turn on Allow Web Sites To Choose Their Own.

The security sandbox setting worked. I originally had neglected to restart Firefox. I tried again, closed and restarted, and Firefox now displays the correct character set.

Thank you for this suggestion.
