IE strips away Firefox ad blocks

I am using IE destroyer in my website (www.freepalawan.com), and on the whole it works fine. The splash banner is very efficient. The problem is, the Get Firefox ad in the block section would not appear. I have encountered this action too in my other website (a blog, at www.palawenyo.com), when I used an IE browser before. After some research, I read somewhere that IE does have a way of blocking FIrefox ads from appearing when its browsers are in use.

I'm sure all you creative Drupal programmers out there have a solution for countervailing this underhanded action by Microsoft. I am satisfied with the existing splash banner, and it functions pretty much like an ad banner too. But it seems to me to be wasteful to have feature in a module that doesn't work like it should. Plus, I'd really love to kill Bill --- 's browser because I was its longtime before I switched over to open-source (Drupal, Firefox, Opera, Ubuntu). I'm sure many PC users out there would love to do that, too.

Thanks in advance, and more power to Drupal and all other open-source communities!
