Is it possible to restore the default fonts from earlier versions of Firefox to use on web pages for version 21 instead of using the new shipped Open Sans and Charis fonts?

Smo,

That is incorrect, you can change the fonts used in content to your own choosing albeit only through advanced about:config preferences. This is not recommended.

Change these in about:config;

  • font.name.serif.x-user-def
  • font.name.sans-serif.x-user-def
  • font.name.sans-serif.x-user-def
  • font.name.monospace.x-user-def
  • font.name-list.sans-serif.x-user-def
  • font.name-list.sans-serif.x-user-def
  • font.name.serif.x-western
  • font.name.sans-serif.x-western
  • font.name.sans-serif.x-western
  • font.name.monospace.x-western
  • font.name-list.sans-serif.x-western
  • font.name-list.sans-serif.x-western

I've never tried changing these so you are at your own risk here.

You can not change default fonts, but - if that's any help - you can change their default size.
