additional.css not working

[worried]

It's working fine for some css I added but not for the blog text editor

.editor_textbox textarea, .editor_textbox iframe {

font: 13px;
}

Firebug lets me increase the font size but adding this to additional.css does nothing.

Try using font-size: 13px;

That did it. Funny I'm using "font: 13px;" elsewhere and it's working

Not if you are using it in CSS. It must be being over-ridden by something else.
