lithopsian的代码（最初位于http://forums.mozillazine.org/viewtopic.php?f=23&t=1977593&start=30）
显然，这在现有扩展中，但是可以将代码放置在您喜欢的任何位置。
这样的CSS：
#urlbar
{
-moz-binding: url("chrome://NoTabs/content/NoTabs.xml#NoTabsUrlbar");
}
.autocomplete-richlistitem
{
-moz-binding: url("chrome://NoTabs/content/NoTabs.xml#NoTabsRichlistitem");
}
像这样的绑定替换了两个关键方法：
