Well, I too use FireFox, and have been very pleased with the pop up stopping compared to the Internet Explorer. But , to tell the truth, I still use IE. I cant wait to see if this 7.0 comes out and does what they say it will do. Me, I dont think it will, I havent been too happy with IE for quite awhile. IE is pretty much a standard nowadays. Other people still use other clients such as Opera, FireFox, Etc... But the majority still use IE, which in my opinion, will still be more prone to hacker attacks and whatnot.
