I hacked into layout/html/base/src/nsPresShell.cpp, and got to know that
document styles are treated differently for chrome windows and other kinds of
windows. Then I modified the following code in nsPresShell.cpp, and rebuild,
and the results are the same.
line 2137 of nsPresShell.cpp (version: 3.647 FIREBIRD_0_6_1_RELEASE)
if (NS_SUCCEEDED(result)){
/*if (nsIDocShellTreeItem::typeChrome == docShellType){
return NS_OK;
}*/
}
If these lines of code are commented out, it will continue to load user
preferences about styles.
Other styles, like link colors, are changed, while the background of iframe is
still white.
