/*

*/
@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* set default namespace to XUL */


/*

*/

/* Make all the default font sizes 20 pt:*/




/* Make menu items in particular 15 pt instead of the default size:
*/
* {
font-size: 9pt !important
}

/*
* Give the Location (URL) Bar a fixed-width font
*/
#urlbar {
font-size: 9pt !important
font-family: SimSun !important;
}
