Buying a new computer, the white background now hurts my eyes and I've changed the color in Windows so all white become a cream color.
Well, yes, that's a possibility. You could also take on sun glasses. Another possibility might be to reduce the screen's brightness. But why simple when it also works complicated...
Paste one of the following rules to your userContent.css (Edit > Configuration > User-Defined StyleSheet):
1) This will only effect empty browser windows:
@-moz-document url(about:blank) {
body { background-color: Window; }
}
2) This will effect all pages that do not have a background color set:
body { background-color: Window; }
3) This will effect ALL pages:
body { background-color: Window !important; }
You have to restart km to make changes in your userContent.css take effect.
'Window' is the symbolic name for your OS's window color, whatever it actually is.
