Comment 2 for bug 1025902

One solution is to add a file called "usrContent.css" and paste these contents in there (source: http://thefire.us/archives/80 ):

input {
border: 2px inset white;
background-color: white;
color: black;
-moz-appearance: none !important;
}

textarea {
border: 2px inset white;
background-color: white;
color: black;
-moz-appearance: none !important;
}

select {
border: 2px inset white;
background-color: white;
color: black;
-moz-appearance: none !important;
}

input[type="radio"],
input[type="checkbox"] {
border: 2px inset white ! important;
background-color: white ! important;
color: ThreeDFace ! important;
-moz-appearance: none !important;
}

*|*::-moz-radio {
background-color: white;
-moz-appearance: none !important;
}

button,
input[type="reset"],
input[type="button"],
input[type="submit"] {
border: 2px outset white;
background-color: #eeeeee;
color: black;
-moz-appearance: none !important;
}

body {
background-color: white;
color: black;
display: block;
margin: 8px;
-moz-appearance: none !important;
}

I'm not sure if we can make the CSS file system-wide or not, but I still don't like the idea of modifying something that doesn't belong to the theme through installation of the package.
