Diabling javascript just to get rid of popups is really not a good solution. That's like disconnecting your phone so that you will not have to get calls from telemarketers. You will also miss a lot of other phone calls you might have wanted to get.
This is some page a search turned up that lists a few examples of content that requires javascript

These small popup stopper programs don't hog enough system resources or hard drive space to really matter at all... escpecially a tiny one like PoopOops. And you can easily turn it on or off by clicking the icon in the taskbar... If you were using the methind of disabling javascript, you'd have to go into the security settings of Internet Explorer (if that's what you use to browse).
Well, the earlier versions of PanicWare were pretty nice... And since probably 90% of people have (want to have?) javascript enabled, a popup stoper is a pretty good solution.
