Which encoding is selected when you see the hex code?

  • Firefox > Web Developer > Character Encoding
  • View > Character Encoding

You can try to set the Boolean pref gfx.font_rendering.directwrite.use_gdi_table_loading to false true on the about:config page.

Can you post a link on a page where you see it?

If you see such a box with hex code in it then that means that Firefox can't map a character to a specific font and you have to install a font that covers the affected characters.
