Mozilla's undetectable document.all support

Next version of Mozilla/Firefox(/Thunderbird?) will support IE's proprietary collection document.all in a undetectable way, i.e. this will (still) not work:

if ( document.all )
    alert( document.all );

But this will work:

alert( document.all );

Stay cool, guys. It is NOT encouraging web developers to code in non-standard way, but just a way to support legacy Web sites that assume everyone use IE.

For web developers that care about standards, they always use document.getElementById (or others methods like getElementsByTagName or getElementsByName).
