Firefox "transfering data" status not going away after appending SCRIPT element

Hit the "Get Source" button in Firefox and the script will work properly displaying a "Please Wait" message to the right of the button and displaying "Done" when it's done. However Firefox will still display a message "transfering data" in the status bar which doesn't go away.


scriptgrabber_script.php:

<?php

function jsescape($string) {

$find = array('\\', '"', '/', "\b", "\f", "\n", "\r", "\t", "\u", "<", ">");
$repl = array('\\\\', '\"', '\/', '\b', '\f', '\n', '\r', '\t', '\u', "\\<", "\\>");

$string = str_replace($find, $repl, $string);

return $string;

}

$path=strtolower($_REQUEST['url']);
$contents = "";
if(substr($path,0,4)=="http"){
$contents = @file_get_contents($path);
}
$contents = jsescape($contents);
echo "requestDone(\"".$contents."\");\r\n";
exit(0);
?>

Mozillazine forum has 20 or so posts about this with no good solution;
it is probably a browser module that hangs when you write to a
document while it is loading. I had a similar problem and struggled with it;
but when I upgraded firefox and seamonkey it quit happening.

It is still occurring with an older mozilla, though, and probably
on a lot of user's machines. I'll keep looking, but try an upgrade.
