I love that the syncronisation works so fine! And the whole concept with Identies and so on.
Not so good, or annoying is:
On some sites with newer technology the Roboform fill in does not work, wich is anoying. Also, in these cases, the "show password" (for filling "manually") does n ot work sufficen tly either, sometimes better, often worce, unfortunatly, though I thing it has been better than it was for say some year ago, when I nearly left Roboform.
