Why are linkbuttons not grayed out when disabled in FireFox?

Question

Why when I set enabled=false on a button does it not render correctly in Firefox? Instead of graying out the link it is still blue.

[UPDATE]

ASP.net already rem

From W3Scholl, "Enabled" Property isn't standard property of XHTML 4(It's Microsoft standard.). You should remove href property from hyperlink or using my following code

// cancel click event.
LinkButton1.Attributes["OnClick"] = "return false;";
// set css to display same disabled link in all browser
LinkButton1.CssClass = "LinkButton_Disabled";
