Title: Add another preference check to detect if web fonts are disabled in Firefox

This PR adds a check of the preference `gfx.downloadable_fonts.enabled`. Setting this to false currently doesn't trigger a warning that the PDF file might be displayed incorrectly, even though most PDF files I've tried fails to display correctly when `gfx.downloadable_fonts.enabled = false`.

This a follow-up of #2425.
