Remove the ad banner from your Hotmail inbox
One thing you might not like is the big vertical billboard on the right-hand side of your inbox. Fortunately, just like GMail's block of text ads, it's easy to hide. All you need is the Windows Live Ad Remover Userscript. Yes, Hotmail guys, I really DO have a very clean inbox!
Chrome users can simply click the install button at the top of the page. Firefox users will need to install the Greasemonkey add-on first and Safari users need Greasekit. Opera users who aren't sure how to install Userscripts can check this post for help.
Internet Explorer users can try either Trixie or IE7Pro, though I didn't have any luck with this particular script in either one.
