Why does noscript keep saying this on my hotmails??

It keeps saying "noscript filtered potential cross site scripting attempt" it keeps saying that when I go on my hotmail accounts, wtf??

This should help http://lmgtfy.com/?q=noscript+filtered+potential+cross+site+scripting+attempt

XSS is a way to redirect you to a malevolent website from a legit one.

I've used noscript for a long time and never had that when using hotmail, sounds suspicious.
