Only black text appearing when I make a post

[XxFuRy2Xx]

As of late nothing but black text appears when I attempt to write out a post. This makes it pretty difficult to actually write out a post. I usually have to use MS Word and then copy and paste. Although once I hit the "submit post" button the text appears as it should. Anyone know what might be causing this?

I'm using Firefox 3.6 on Mac OS X 10.6.2.
