Description:
Since some time (one or two weeks), unfriend finder damages "like", "play" (on Youtube embeds) and other "internal" links on the facebook page what causes my browser to open AJAX urls.
I mean, Opera opens the link http://www.facebook.com/ajax/ufi/modify.php when I click on a like link (instead of liking it!).
For me, this is a showstopper (as I can use facebook just 'read-only' with unfriend finder activated). I completely disabled it at the moment.
