Like everyone else with Safari I'm now getting pop unders. The great thing is I never even realised I was getting them because I never close my browser window, and when I quit I don't use the "close" button, I hit Apple-Q. I managed to see one today by accidentally double-clicking on the title bar (causing a minimise).
Strange idea these pop unders.

If you were using Windows it'd be hard to ignore them completely. Surfing around where there are popunders for a while, the taskbar would get rather crowded.
JS bad
I browse with JS disabled, and turn it on for the few sites where I actually want the JS-enabled features. Disabling JS also eliminates most advertisements.
