The $ajax->link votes example was not working in FF3 for me. I had to change the code to the following to get it working:
echo '<li>'.$ajax->link('up', '/comments/vote/up/'.$comment['Comment']['id'],
array('update' => 'vote_'.$comment['Comment']['id']), null, false).'</li>';
echo '<li>'.$ajax->link('down', '/comments/vote/down/'.$comment['Comment']['id'],
array('update' => 'vote_'.$comment['Comment']['id']), null, false).'</li>';
For some reason the li tags in the link title caused the link not to work.
It's working just fine in IE7, but in FF3 the vote links simply ignored any clicks on them.
