In my website, I preview any link with a tooltip, but when its facebook or meneame.net, for example; they block it and open their webiste in you website's current window.
Exanple <iframe src="http://meneame.net/bababa"></iframe>
How can i prevent that? i mean, maybe open it in a '_blank' page instead would be perfect for me. is it possible?
PD: the option of trying to detect which URL is about to be opened its not valid for me as long I don't know all the websites that do so.
