some web pages background color don't choose their own colors

[Jose]

Binary package hint: firefox-3.0

In spite of I've marked the checkbox "Allow pages choose their own color, instead of my selections above", (Edit-> Preferences-> Content -> Colors) some pages use the background color I've choosen for personal background color.

1) RElease of Ubuntu
Description: Ubuntu 8.04.2
Release: 8.04
2) ??

3) I expect each wep page uses their own background color if checkbox is selected.

4) Some pages don't choose their own background color and uses my background color. (Example www.emol.com)
