Arial Black, Rockwell Bold, Cooper Black fonts don't render.
This has been a problem since FF4 and has been unresolved. Please fix. Note: when hardware acceleration is turned off (or more specifically gfx.direct2d.disabled is set to true) those fonts render. This is only a problem on Win7 (32 and 64 bit)

You need to add specific font attributes to make Firefox use such fonts. Firefox places all fonts that belong to a specific family in one group on Windows 7+ and you need to use a selector like "font-weight:900;" to select Arial Black from the Arial group. Otherwise Arial is used. You will have to find out which selectors to use for Rockwell Bold and Cooper Black to make Firefxo use them on Window 7.
- bug 644385 – Arial Narrow, Arial Black fonts do not show on page (comment 8)
Those CSS hacks are a joke and aren't foolproof. They don't actually use those fonts, they just alter the Arial font to look similar to Narrow and Black. This has been going on since version 4 and now we're at version 7. Can't anybody use their brain and fix this?
