Here’s a quick hack although many of you probably know this:
1. Visit Hotmail.com
2. Login
3. The resulting page says that Hotmail cannot identify your browser (Typical MS style, if you think it’s better than your own, pretend it doesn’t exist! Try ignoring Firefox now!). Near the bottom of this page is a link which says “continue anyway” or something on that mood. Click on that and you are good to go. And use the new 0.4beta of Chrome for better performance.
