For all of you still using IE, you should switch to Firefox
a open source, cross platform browser. It is also extensible. I have extensions on my browser to allow me to control my music player from the browser, one that displays local weather conditions, one that randomly renames my browser, and one that blocks ads among others. It has popup blocking built in, and is not vunerable to spyware installation via ActiveX.
Seriously, check it out.
