Hi ! I tried yesterday with Chrome 24, Safari 5.1 and IE 9 (all under Windows) and I got the same problem with all of them... but I don't know why today it seems ok.
In Firefox 18 with Noscript I'm getting a clickjacking warning:

In Chrome 24 I noticed the link appears when clicking the G+ button but before the user click the share button.
And can I suggest a new feature for the plugin?: the link doesn't appear until the user click on all the social buttons ?
Thanks !
