FF Ignores CSS Options

[homeuser]

I am helping someone with a website. We want to have the first letter of the first paragraph larger and in a distinctive font.This is the CSS link:
<link rel="stylesheet" type="text/css" href="css/firstbigletter.css" />

This the external CSS:

.firstbigletter {
font-family:"Typo Upright BT", "Times New Roman", serif;
font-size:45px;
font-weight:normal;
line-height:80%;
letter-spacing:-6px;
}

Control Panel - Fonts shows that the first font is there (see attached). But FF won't recognize it and displays the letter in what appears to be Times New Roman . IE does recognize it and displays the first character in the Typo Upright. What must be done with FF to get it to properly use the CSS?

Thank you.

The font is spelled "TypoUpright BT". The problem was in spelling it as three words instead of two words. Now that is working properly and being selected. Question: How would I embed the font in the CSS, as you suggested? That would be quite helpful if other don't have that font.

There is also a problem in testing other fonts, using the TypoUpright BT as a secondary font. In this case, none of the fonts are recognized (it defaults to something plain):

font-family: "Palace Script MT", "TypoUpright BT", Gigi, Harrington;
font-family: Gigi, "TypoUpright BT", Harrington;

Any suggestions as to why these two don't work at all (Control Program shows all fonts on the machine).
Thanks

Do the browsers support the font file formats?

Also, maybe the fonts don't contain glyphs for the characters you want to use (some specialized fonts may only support numbers, upper-case letters, or similar).
