Why am I getting pop-ups even though I have "Block pop-up windows" checked under content?


This just started in the last week. I have not had this problem before and I went back into the Options settings to make sure the box was checked.

Specific web sites repeatedly? Or do they seem to be random websites?

Question owner

I just opened my Mozilla browser and went to email, clicked on the notification that I had a reply to my question, and this window popped up: http://newsdaily7.com/jobs/?t202id=62361&t202kw=us.mg4.mail.yahoo.com This "newsdaily7.com" been one of the ones I have seen before.

And you are using Yahoo Mail thru Firefox?

Do all those popup windows show that =us.mg4.mail.yahoo.com at the end of the URL, or something similar?

If so, I can't only guess that Yahoo Mail is getting around the popup blocker.
