Mozilla does not support the "defer" attribute of the <script> element (http://www.w3.org/TR/html4/interact/scripts.html#adef-defer).
do we care?
See bug 28293 (RFE: defer attribute not supported on script elements) This is a dupe, though it doesn't look like it will be added soon as other things have taken higher priority. The blocker bugs should be removed from this bug and added to bug 28293. *** This bug has been marked as a duplicate of 28293 ***
Oh, didn't notice the dupe. My searh didn't include bugs which were resolved LATER.
vrfy. i don't blame you, see bugs about 'later considered harmful' :-(
