SYFer writes "Shortly after upgrading my Macs to OS X 10.3.8, I noticed that I was getting pop-up ads on Safari. It had been so long since I'd seen a pop-up, I completely forgotten how annoying they can be. I went over to Apple's Support site to see if there was a relationship, but learned that the timing is just a coincidence (even though there's a lot of the usual FUD and flailing of arms in the discussion forums). In fact, it turns out that the pop-up advertisers (what's the proper denigrating term here?) have finally defeated the pop-up blocking functionality found in many browsers. MacFixIt is running a front page article on the topic and says 'Contrary to initial reports, this problem isn't limited to Safari; subsequent reports have noted pop-under ads victimizing a number of browsers that provide pop-up-blocking features, including the latest versions of Safari, FireFox, Mozilla, OmniWeb, and Camino.'"
