This script does just what it says.
Like the previous commentator, the search box is slightly too large and overlaps the bottom of its containing div (English version at least). This, I would imagine, is due to poor code on Microsoft's part though.
I'm using this script with Greasemonkey under Firefox 3.5.4pre (aka Shiretoko), with adblock+ extension enabled, and it does it's job as advertised... If only Microsoft would have had it setup so that my little icon didn't go offscreen... but hey, it's better than having my email cut off!
Works nice. But since this is not your script I installed it from userstyles.org. lol
Hey, apologies for my bad review before, it's working great now thanks.
