I'm having trouble getting WWW::Mechanize::Firefox to submit data to a site that uses JS on the return page that prevents WWW::Mechanize from being useful. Below is the code I'm trying to use for WWW::Mechanize::Firefox. The browser loads the initial page, but the form is never filled out before the submit button is clicked. This is on a Windows XP system with the latest version of Firefox, Strawberry PERL and MinGW. 
use strict;
use WWW::Mechanize::Firefox;

my $url   = "http://tools.immuneepitope.org/tools/bcell/iedb_input";
my $agent = WWW::Mechanize::Firefox->new(
    activate  => 1,
    autoclose => 0,
);

my $method = 49;
my $seq = "ARRRSFASDATRASDFSDARASDAGADFGASDRFREWFASCDSAGAREW";

$agent->get($url);
if ( $agent->success() ) {
    sleep(5);
    print "Retrieved $url\n";
    $agent->form_name('form1');
    $agent->set_fields( 'sequence' => $seq,'method' => $method);
    sleep(5); 
    $agent->submit();
}
