Actually it's not the CSS that is the problem, ptc is the embedded font name, while PETC is font file name, the problem is Firefox under normal settings doesn't allow embedded fonts, you must have downloaded the PETC.ttf from my link above allowing it to be displayed when you change the font to PETC. To allow Firefox to display embedded fonts, you have to go to about:config and change the security.fileuri.strict_origin_policy to false.
