I recently able to use IE 7 because I was not having SP2 -Xp version. But after working on IE 7 , I must say Firefox is the best. But my other family members are not used to Firefox so i thought why don't we have a standard IE7 theme for Firefox. Thus while searching i came to know about nice good stylish IE theme for Firefox 2+.
MyFirefox- New IE7 theme
Previously I had came across many IE 7 theme but I believe this is the one I was searching for. The best thing about it is that It works in Linux too. So Linux users can also take feel of it. It looks exactly as IE 7 where Authors must have spent many sleepless nights.
