This strategy works for me. Determine what content will be visible on the webpage only if the login succeeds. Then repeat the login step until that content is visible. Once it is visible, you know the login succeeded and you can do stuff on the next page. Plug in (1) your own url here, (2) whatever content should be visible only when the login succeeds, and (3) your lines of code you want to use once the login succeeds. Let me know if this is useful. 

use WWW::Mechanize::Firefox;
my $mech = WWW::Mechanize::Firefox->new(autoclose => 0);
$mech -> get("your own url");
my $count = 0;
my $retries = 100;
while ($retries-- and ! $mech->is_visible( xpath => '//*[@value="your 
+own content"]' )) {
    $count++;
    print "count: $count\n";
    sleep 1;
    #Do your login stuff here.
    if ($mech -> success()) {
        #Do stuff only once the login step succeeds.
    }
}
die "Timeout" unless $retries;
