XSS @ http://mail.yahoo.com

"Signed out*" of yahoo &...

*Actually it did NOT sign me out.
(I did nothing with the XSS prompt warning.)
It does go to a "login" page, https://login.yahoo.com/config/login_verify2?logout%201&.direct%202&.done%20http://www.yahoo.com&.src%20ym&.intl%20us&.lang%20en-US#786451552263..., but in fact you are not logged out at that point.

On this screen, there is again a "Sign out" link, & if you then click that, there is no XSS warning, & you are in fact logged out at that point:

Fast answer that WFM, may not suit you:
Since mail is the only Yahoo service to which I log in (I use others, but as a guest), I merely used HOSTS to block www.yahoo.com.
Then signing out of mail, the annoying redirect to main yahoo page gets a "can't connect" message. Done. Go elsewhere.

If you use other Yahoo while signed in, this wouldn't work, and doesn't explain your original XSS message anyway.
But it surely simplifies things for me.

Appears it is happening in FF >16

Same with equivalent versions of SM? Newer break, old works?
If you can nail it down to Fx > 16 only, sounds like either a MZ bug or something for Giorgio to look into.

Yes, equivalent version of SeaMonkey (2.14a).

If no response soon, perhaps you might PM Giorgio to see if he can reproduce, find >16 bug, whatever?

I too started getting this 'confirm password' from Yahoo mail, when logging out. I first noticed it after upgrading to FF 17.0. I've no idea if it is a NoScript issue, FF or Yahoo. Is it more or less a coincidence that I'm also reading about a Yahoo mail XSS exploit so much in the news at the same time? Any clarification would be greatly appreciated!
