I generally use the same point size as was selected in the OS's desktop settings. Obviously, edit that font-size: 9pt !important to a value that suits you. * Do not remove the line - it's required for correct url(' ') /* set default namespace to XUL */ In this folder, create a text file named userChrome.css
