Twice recently I have tried to buy something on-line, have been told I need to "Verify by Visa" [VbV], have seen the VbV form come up in a frame in the merchant's page, but then to be replaced in the frame almost immediately by a portion of the merchant's own log-in screen.
Anyone else had this experience? Is it a bug with FF, VbV or the merchant's website?
Specifically, I am using Firefox 4.0.1 (works with everything else), have already logged into the merchant's website, registered with VbV some time ago, and the merchant is LCN (= Low Cost Names http://www.lcn.com) who provide a domain name service. Both failures were with LCN, and after I moaned to them the first time two months ago nothing has changed.
None of this alters the fact that VbV (and equivalent Mastercard system) is a PITA. I don't know what it adds.
