Recommend Firefox to IE visitors to your site
If you haven't seen ExplorerDestroyer yet, it's a site that offers some fancy ways to either encourage, push or insist that visitors to your site download Firefox. The code will not display a promo if you are already one of the Firefox enlightened and it's a good idea but perhaps a little heavier than I wanted for my own blog. Not to mention a bit violent sounding for people like me who just want to advocate a faster web experience.
If you are viewing this site in IE then you see the advert on the right urging you to give Firefox a whirl. I used a conditional comment called If IE to only display a Firefox enhanced with Google Toolbar promo box by pasting the below code into my blog template. Feel free to copy to your own blog. You may want to change the Adsense ad client id to your own (if you have one) so you get credited with the $1 bounty currently paid for helping folks switch over to Firefox. Enjoy.
