Got the message in the browser via an browser error
[NoScript] Blocking refresh on unfocused tab, http://www.ad.nl/->http://www.ad.nl/
Read on this threat: http://www.dslreports.com/forum/remark,24300913 (link poster = visomiser) NoScript protected me against “tabnapping”,
because trying to go there gets: a 404 Page error - page does not exist anymore or has been moved (could have read PHISHING page etc.)
Use NoScript and RequestPolicy extensions in a firefox browser and feel more secure,
