I occasionally get other pop ups but it's usually "Uncover the Net" trying to sell me stuff I don't want. This happens several times each day.
try Adblock Plus add-on and then install Adblock Plus Pop-up Addon
(Adblock Plus is required to work the Adblock Plus Pop-up Addon. If you get a message saying additional items required it means that you don't have Adblock Plus installed)
Thanks so much Ideato. I will mark it Solved in a couple days after test driving.
