Pop-ups in Yahoo's webmail

I use Yahoo's webmail with Windows Vista, Firefox and NoScript. This works well, but I get a pop-up window a number of times each session, and it's an always-on-top window. The program asks for permission, but if I agree my virus/spyware programs refuse it. The two sources of this pop-up seem to be ad.bluelithium.com and ad.yieldmanager.com, from servers run by Yahoo.

On the net, "free" webmail actually means "paid for by advertising" but you can try installing another Firefox add-on, Adblock Plus. Yahoo uses "ad matching", which is also known as "behavioural advertising": it tracks what you look at and provides more targeted adverts. If you regard ad.yieldmanager as spyware then you can use software such as ATF-Cleaner and SuperAntiSpyware to stop it. See the Elder Geek site for an example.
