It doesn't look like that supports ways of loading Firefox, as for some reason the ! operator isn't doing anything.I tried this and it didn't work:<style><!--[if IE]><link REL="STYLESHEET" TYPE="text/css" HREF="/ie.css" Title="TOCStyle"><![endif]--><![if !IE]><link REL="STYLESHEET" TYPE="text/css" HREF="/firefox.css" Title="TOCStyle"><![endif]></style>Also tried this which did not work:<!--[if IE]><STYLE TYPE="text/css"> @import url("ie.css") </STYLE><![endif]--><![if !IE]><STYLE TYPE="text/css"> @import url("firefox.css") </STYLE><![endif]>
