I just made an interesting discovery, please see this site: www.ie7.com (or image below). Never think that this is for IE7.0! It contains only one accessible page and looks like below:
On top of page there's one sentence reads "Neither this site nor Mozilla is connected with Microsoft.", and the huge Firefox icon links to www.mozilla.com/firefox/.
As with following "Kill Bill" pic, this deed was certainly done by Firefox fans.
As you can see, I'm using non-microsoft products so I could laugh so happily :-)
